i rattled can my front lip and was wondering if i can sand it to make it smooth with a 1200grit sand paper? because i see little bumps on it..and also for clear coat what grit should i sand it? ive searched and couldnt find anything if someone could give me some tips id apreciate it

 

it looks like crap! hahaha

 

I know with automotive paint, you are able to sand imperfections out of the base-coat before you clear, I'm not too sure about spray paint, but i don't see there being a problem with doing so, just be gentle so you don't sand through.

Personally, i'd recommend going no lower than 1500 for sanding base coat. If the 1500 doesn't cut it you can go on down to 1200. But as you get into coarser grits, sand more and more carefully. I wouldn't recommend going to 1200 cuz when you clear over 1200 you may be able to see tiny little scratches in the base.

As for sanding the clear, I usually use anywhere from
1500- for a lot of orange peel
to
2500- for hardly any orange peel
Depending on how bad the orange peel is, so judge accordingly. And hard-blocking always makes it look better, though it'll be tough on the rounded surface, so again, just take your time and be careful. Also, buffing is going to be a bitch on your lip, so do your best on spraying the clear so you hopefully won't have to sand the clear at all. If you have any "in depth" questions, just message me.

good luck

 

^ thanks for taking the time im going to go try it today and i will post more pics as soon as i get it done

 

i would wetsand with 1500 then throw another light coat over it then clear

 

No problem, I look forward to seeing how it comes out.

 

lol i was an idiot i basically sand it down..primered it..and i didnt sand the primer(should have) i just laid some paint on it now it looks like crap..and i tried sanding it down with 1500grit after the paint it it looks the same lol you can see the little cradles. im gonna go ahead and resand the whole thing down til its smooth and then retry it again

 

lol yeah, definitely take it back down to a nice smooth surface. From there, you can decide to either re-primer it or just spray the base-coat down on the newly sanded surface depending on how nice it comes out. No offense but the whole purpose behind primer is to get rid of any flaws by sanding it down, unfortunately you had to learn that the hard way lol. But hey, life's full of learning curves.
Hope your next attempt comes out good

 

you know paint doesn't really go on that thick, wet sanding even with the smoothest one, will take off too much clear if not careful. Also, you might get sand marks, so yes polishing will be a beeaach.

 

as stated above use 1500 then another coat of cleaar, but honestly i would use 2000 afer another coat to be safe.
