hey guys
i dont know if this is the right forum
but here it goes

i gotta new bumper from a member here, and i was gonna prep and primer it so it could save on painting costs

i think the preping went well
used 180 wet, then 400 wet
came out pretty smooth

then i put some primer on it

here is the question
the primer doesnt "color" well compared to other color spraypaints, it leaves a couple thin blotches of blue (old bumper color)
it has a layer on it, but the blue shows through

i have a few splotches on my primering, and was wondering if thats ok?
does it have to be solid primered? leaving no splotches?

its my first time doing a bumper shaving

thanks

put more primer on, then sand that down after it dries.

I would buy a sand blasting kit from Harbor Freight and sand blast the bumper first. You'de need an air compressor too. Then sand it down by hand to give it a nice and smooth finish. Then do the rest. This is what I will do with my bumper. It needs to be repainted and what not.

I'll buy that sand blasting kit. Not much money, like $50. Then I'll sand blast the crap out of my bumper. I'll need to find some cheap sand to use. I want a rough rough finish 'cause I need to smooth out a lot of chips and scratches. My bumper is 1/4" thick, so there won't be a problem.

Anyway, just sharing...

when i repainted my front bumper, i used 80 dry, 220 dry, 320 dry, then 400 wet...turned out really nice, without any paint left over, and smooth as heck. then primered, sanded again, and painted. no left over paint from before. turned out nicely.

Hmm... That didn't take too long? I may do that if it's not too time consuming...

WAIT!!!! Before you go any further. MAKE SURE YOU DEGREASE THE SURFACE!!! DEgrease , wet sand with 400 grit, the re primer. Make sure you are using sandable primer. Repost after you do so.
