Hey Froggyman, I have sprayed a little before, but not a lot. It is something I normally leave to a paint shop, but I don't have the money for a £1500+ paint job, so I thought I would have a go myself!
I managed to get a coat of the colour on tonight, so that will dry off and I will wet sand that tomorrow before putting on more coats of colour.
Painting is relatively straight-forward, just very time consuming hence the cost... Youtube is great for learning the basics and then it is all about technique and practice and lots of patience (I lack the last one!)
I am lucky in that I have a compressor, spray gun, Dual-Action Sander and then it is just lots of filler, 60 and 180 grit sandpaper, 400, 600 and 1200 wet and dry paper, and then filler-primer and paint.
I will go through what I did step-by-step when I have finished and hopefully inspire you to have a go!
As a teaser, this is the first coat of colour, it is like a creamy-white, (BMW mini pepper white was the nearest).
I will take some more once all the colour is on tomorrow.
And yes, you can still get cellulose but you have to go to a proper paint supplier - I toyed with ordering from the web, but opted to go for a local supplier here. I have probably spent around £350 on materials (sandpaper, filler, primer, paint, thinners etc), and about 2 weeks evenings and weekends prepping on and off with a few hours here and there. The bonnet took a while to get right and I made a scoop in that time as well!
Even the scoop came out okay...
