spraying tips

[em1-cooper]

Have decided to tackle spraying the front and back bumper as well as a wing and side skirt. The paint, thinners and hardener is on its way. Have a compressor and all that. Just looking for some tips on the actual painting. Never sprayed anything with an air gun before, just aerosol. Any help would be greatly appreciated

first of all prep it properly.

once you prime it wet sand the primer down to a 600 grit until its super smooth. some people use 800 grit but 600 works well for me.

basecoat is pretty basic to paint and you shouldnt have any problems. how ever.

1 light coat to tack, then 2 wet coats with a 50/50 overlap. if its metalic paint, give it a dust coat just after the 2nd coat (this allows the metallic flakes to stick to the paint instead of laying flat giving a better finish)

the clear coat.

same as the basecoat 1 quick light coat, straight followed by a wet coat 50.50 overlap.

15-20 wait then 2nd wet coat. the key with clear coat is to give the gun plenty of air if using a HVLP gun.

- take your time, cant rush paint
- if it goes wrong dont worry its sandable and redoable
- clear coat is prob gona be ur biggest challenge to achieve without *orange peel*
- if it is a little orange peel, not to worry,1500 and 2000grit with compounds can solve that no problem.
- if you get a run on the clear same as above dont worry, as long as it aint ran the basecoat you can sand it down and buff it, never notice it.
- use plenty of panel wipe before laying the basecoat, reactions are a F*****
- and make sure to tack the basecoat before clearing the panels.

Anything else just ask mate.

Hope this helps.

@ Nuno very good advice!

And make sure to read the datasheet, the clear-coat often has a time window in which it must be applied following the base-coat or you can have problems later on.

i have a couple of bumpers to do soon so may make a detailed write up from start to finish.
