In relation to my other thread from a few days ago about painting my bumper.
I have primed it with aerosol paint from paint factors, so far with high
build primer, rubbed it down and smoothed it up nicely. Showed a few niggles
and imperfections that were soon sorted followed by some more high build
primer. I've put 2 coats on, just wondering how many is nescearry ? Tommorow
I will put the regular primer on and rub down again again how many coats ?
Then following day the base then laquer (just after some info on how many
coats to be honest)

Also is it ok to leave the primer on whilst still using the car (bumpers on
car now) would rain affect the primer ? or basecoat without the laquer
obviously ?

Thanks
