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 ?

Enough coats until it is possible to rub down the primer with no low spots,
and without rubbing through.

Tommorow I will put the regular primer on and rub down again again how
many coats ?

No need to put another primer on after high-build.

Then following day the base then laquer (just after some info on how many
coats to be honest)

Wait for a good few sunny days to pass. Primer can and does sink - don't ask
me how I know, I just do .

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 ?

It'll be fine with just primer. I'd not leave base too long without clear
over the top, although normal clear offers little UV protection.
