Some advice please for a complete beginner.

Building a rally car with my lad and we are looking to paint it ourselves to help with the (limited) budget. Might as well learn now, so we can repaint / replace panels as the season goes on.

Shell is away at the moment getting blasted and will come back with primer. We have a second car that has been stripped for parts and will start practising on the wings / bonnet of that.

I'm struggling with what I actually need to buy. Base Coats, Top Coats, Clear Coats, Activators, Hardeners?

We will be painting the car White.

What will be the easiest option?

I think I'd rather spray it. Want to do the full inside of the shell including roll cage.

I'll do as suggested and drop in to a supplier and talk it through.

I dropped in to my local paint supplies shop and had a good chat through all the options.

Settled on Quick Air Drying Acrylic.

Im due to pick up the shell tomorrow. Started putting the primer on the bits that didn't go for blasting. Plastic bumpers etc.

A question though - we have sanded everything and it feels really smooth, but after spraying the primer, it feels rough. Sanded back to smooth again and it seems ready for the Acrylic, but is it the settings on the spray gun that makes the primer feel rough?

Thanks.

Its not in a spray booth, just my workshop, but i dont think its dust. The imperfection is uniform.
Thinned as per instuctions.

Im guessing it will be technique. To far / fast.

I'll have a play about with the spare wings again.

Worst case, and it feels rough when i use the Acrylic, can it be sorted by sanding and polishing?

Thans for the replies. A bit more prep work today, sanding and filling small dents. Tomorrow we plan a final spray of primer and on Sunday we will start with the White paint.

Method advised by supplier when doing the White is an anchor coat first, then a 3/4 coat and finally a wet coat.

Wish me luck!

Just a little update. The finish is by no means professional, but its quick and easy to touch up when it's bounced off hay bales!
