ok i had this lip in my garage for awhile and now just got around to painting it. it looks like it has some deep scratches from the person before trying to sand it. it almost looks like its 100 grit.

can i just spray primer over it and then paint it? will that cover the marks made from the 100 grit? or will i have to go finer to finer grit to get it out?

 

120grit, 300 grit, 600grit, 800grit, 1000grit, primer, paint, clear coat.

Is that the only way?

 

I agree try going finer before your prime and paint

 

i already painted it thinking it cover it

so i guess the only way to sand finer and finer?

 

there are a ton of threads on this, search

x10000

if u try to paint it with deep scratches from the 100grit the paint wont fill it...so work ur way up to about 1000grit, usually places like pep boys or autozone sell a multi pack of sandpaper that u can buy for like $5

 

ok i got all the scratches out and everythings good. cleaned it, scuffed with 400 then cleaned it again, layed down 2 coats of primer then painted with the base coat. after about 3 light coats of the base, the primer is still showing through, like hte rough parts of the primer.

kinda hard to explain but i guess i forgot to sand down the primer to smooth it out before i painted.

so can i sand it down now with something really fine like 1500 grit to get rid of it?

 

any help?

 

does no one know what im talking about?

 

Make sure you used primer that bonds to plastic. Otherwise you're screwed.

 

ok stated all over from scratch again, reprimed it.

now, what grit should i sand down the primer?

 

ok its not going on smooth. there's really really tiny spots and feels rough on some parts. then some parts look as if its orange peel. i sprayed 2 light coats and 2 medium/heavy coats.

any help

 

wet sand what you have so far with some 400 or finer sand paper,the spray some adhesion promoting primer(they enen have it in a car if you dont have a gun), spray the base, wet sand imperfections,anouther coat of base then clear

what does adhesion promter primer do? is it just the same as normal primer?

 

it is made for plastics its a promoter so the paint will stick....you can paint over it but is is clear

is it really neccesary? i know its probably not more thna 5 bux but i have no job or extra money.

 

the spots are gone now after awhile, it's just orange peel now.

fyi, i havent sprayed any clear yet.

do i just wet sand with 1500 then rubbing compound and buff?

 

where are all the painters at

dont sand up to 1000 grit, youre going to have adhesion problems and will chip off easily...sand it up to 600, shoot gobs of primer, wetsand that then base and clear.

so sand it with 600 first? thne primer, what grit to wetsand with after primer?

i sprayed 3-4 coats of primer and wetsanded it with 1000 grit. and its still coming out all wrong.

im guessing its the spray paint.

 

ur not supposed to sand the base coat

u dont need adhesion promoter if u used primer
then sanded with 400-600
not any higher
