My first build: Kobra

7 Jun 2019, 12:06pm
It is August 2017, 10 months since I started on the build (but 3 months of work).

I convince myself that as I have successfully got this far in the build, unassisted ... I can try my hand in spraying the top coat too.

[Spoiler alert ... 2nd mistake looming]



I mask off the car (but nothing else in the garage!) in preparation for some colour ...



I thought it best to test my spraying skills first on the underside of the boot lid ...



To be fair, it looked OK to me. Good enough to continue.

[Hindsight is a wonderful thing, but foresight is better!]

I did toy with the idea of excluding my mistakes from the build thread (I am sure its only natural), and showing you the 'happy path'. However, I am purposely including them so that any other newbie may be able to learn from my mistakes.

Don't get me wrong, I am not proud of them. But, I have learnt from them. I now know my limits, and when to run ... when to walk.

Anyway, back to the build ...

I used a 50L 'hobby' compressor to spray the car <-- a big mistake :frusty:

From a distance (with squinty eyes) it doesn't look bad for a base coat ...



But on closer inspection, there are imperfections all over the body.

This was because:

  1. My compressor was not powerful enough, it failed to atomise the paint consistently, and instead, randomly 'spat' the paint onto the body
  2. I am newbie without the proper skills or knowledge for such a task
  3. Several other factors that I am still blissfully unaware of

Of course, I shouldn't have attempted spraying my car. I know that now. I guess I wanted to the do the whole build myself. Like I said, I know now where to stop, and pass it to a professional.

Anyway, I had to sand the whole car down again :mad2:

7 Jun 2019, 1:02pm
Still not prepared to throw the towel in, I swapped out my compressor for a 100L one, still questionably on the low side for spraying - but all that funds would allow.

I mask her off again, and try again ...



What I didn't appreciate, but swiftly learned, is how much space you need to spray a car. I am sure this sounds daft, but it was all new to me.



I certainly could do with more space and a better 'dust free' environment.



But the paint was flowing nicely with the new compressor, the finish looking better ...





7 Jun 2019, 1:15pm
And that is how the car stayed for 21 months. I could provide lots of excuses .... work, life, chores, family ... but really, I just got distracted.

2018 came and went. Started to feel guilty around Spring 2019 and finally made my way back into the garage last month, May 2019.

I took the masking off and drove her out of the garage to inspect my handy work nearly 2 years prior. I experienced a 'moment of chuffedness'.



The paintwork is significantly improved from my first attempt. But, to be fair, its not perfect. And I want perfect. I decided (2 years too late) that I need to get her professionally sprayed. But the MoT has lapsed, and I want to be sure there's nought wrong with her, before investing in a spray job.
7 Jun 2019, 1:32pm
I cleaned her up, and refit the lights and fittings, and take her for an MoT. I failed on corroded rear brake pipes. I had them replaced and it then passed.











7 Jun 2019, 1:39pm
Like the original AC Cobra, I wanted a chrome windscreen surround. I probably should have waited until after the spray job, but decided to do it anyway. The chrome wrap was purchased from ebay for about a tenner.







Also fitted the chrome roll bars behind the seats ...



In this last photo, you can just make out some paint fogging / orange peel on the rear drivers arch. There are a few patches like this. Evidently, I need more practise with the spray gun. But for now, the spray shop will deal with this.
7 Jun 2019, 1:46pm
Continue tarting up the fittings. The wipers arms were black, I clean them up, sand them down, prime them and give them a few coats of silver.



Refitted with the new chrome wiper blades of ebay, £20 a pair.

Before and after "cut and shut" ...

7 Jun 2019, 1:58pm
The Kobra is taken for its MOT, fails on a rear brake pipe being corroded (common on these). I fix it, retest it, it passes!! Yay!! :surprised:

I drive it to the spray shop, have a chat, he laughs at my spray job. I decided against saying "Bob up the road sprayed it for me". It gets booked in for a couple of days time.

I have chosen a similar colour to as it is now, but a little lighter, metallic blue with the 2 white stripes. I provided him with a few reference photos to use for the colour scheme.

7 Jun 2019, 2:16pm
The bit i've been dreading. The louvre vents.

First I make a template ...



Using 30mm aluminium strip, B&Q @ £6, a vice and panel hammer, I make the vent surround ...



I then cut the louvres using the same 30mm strip ...



I tack them in (temporarily) with a hot glue gun and realise the louvres are too narrow ...



I loosely slot them into the vent hole to check their fit anyway. Not bad, but not good enough ...



Back down to B&Q, I purchase the 45mm alloy strip, cut and fit. Much better ...



Check how they look offered up to the car. Getting better ...



I replace the hot glue with araldite to fix the louvres permanently (hopefully). Then clean with wire wool, prime and spray with chrome paint ...



Not bad. But I am not happy about the inner joins. You can see a little glue (above). Will have to sort that.

7 Jun 2019, 2:39pm
Today, Friday 07th June 2019, the car has now been in the spray shop for 2 days. I collect her next Friday.

Then, I will fit the MWS wire wheels and spinners.

I've enjoyed your 'Binge Watch' build thread approach. :cool:

I learnt a lot from reading about other people's mistakes.

And I'm sure that others learnt a lot from my (many) mistakes. :rolleyes:

However, I wouldn't beat yourself up for having a go at painting the car.

I know my paint finish is rubbish, but it is my rubbish. :icon_wink:

Hope all goes well for you in the professional paint shop.

Good luck, Paul. :)
7 Jun 2019, 3:56pm
Paul, thanks for feedback. I will keep trying with the spraying, but maybe start on my son's bike next time :)

I can't wait for the phone call saying "Your car is ready to collect". Seven days and counting. Once done, i'll update the build thread (in real time!).

Apparently the spray painting is all about having enough CFM from the compressor rather than the tank volume.

I just ordered a 9.6CFM with spray gun from SGS Engineering - or rather thought I did until a different compressor turned up with a nail gun. About to shout angry things at SGS when I double checked my order. I must have clicked on the wrong picture without realising it. SGS were very nice and agreed to swap for the correct one if I send it back to them.
7 Jun 2019, 4:15pm
A bit of both as I recall, otherwise you'll stopping every other panel and waiting for the pressure to restore.

Mine is this one from Machine Mart.

It has 14.5 CFM which is at the low end of the acceptable 'spray painting' range. I read somewhere to spray paint a car, the compressor would need to output between 14-18 CFM.
7 Jun 2019, 4:17pm
Very nice work indeed.
one tip I read/saw with using a budget compressor for spraying, is to use an appropriate sized gun. I think it might have been MCM who said to get one of the little guns used for small details, as it gives a good spray pattern with cheap compressors. it might take a while to spray with the small coverage it does, but for a DIY job that doesnt always matter.
I look forward to seeing the results from the pro paint job :)
7 Jun 2019, 4:17pm
SGS have done me proud, a lot my kit is from them. Even my 50L compressor (which was swapped for my current 100L one).
7 Jun 2019, 4:18pm
Cheers Kon. Good tip about the little gun. Wish I knew that at the time, would saved a small fortune :)
7 Jun 2019, 4:24pm
Great work, and thanks for posting up the progress, the "binge" approach works too. Fingers crossed that the paint job is as good as you wish for.
7 Jun 2019, 4:29pm
Cheers Barber. I am not sure which is more effort, update as you go, or spend a day updating at once :)

I am confident the paint job will be good. He's done work for me in the past, and does a cracking job. That said, I haven't had a full respray done with him before, but I am hopeful :thumb:

I know this feeling so well: I also know that holding my breath isn't an option....

10/10 for grasping the nettle and having a go yourself, it looked a lot better than anything I could have done, that's for sure! I also loved binge reading your build. Once in a while I look back through my Monaco thread and despair at my feebleness when I see some of my huge 'commitment gaps'. Your car is an absolute credit to you and I look forward to seeing it in the flesh.

Regards, Mick

Nice build, well done ! Like you said with a bit more practice your paint skills will improve, it is a big learning curve !

Like your choice of wheels, not many have been fitted with wires. With some chunky wide tyres they look good on a K/Cobra. Only advise would be to get them spaced in the arches correctly.

Looking forward to the finished photos.
7 Jun 2019, 5:48pm
Thanks Mick, this did make me smile. With 15 kit cars under your belt, I think 'feebleness' is the last way to describe yourself. Well done you.

Just looking at your Monaco thread now. Impressive stuff. I will be keeping an eye on the thread from now on.

Incidentally, for my next build, I am toying with the A352 or the 250 SWB coupe.

Cheers,
Chris.
