I want to repaint my front end over, its not that bad its just I want to have fresh paint because there are some freeway chip marks and a couple white marks...

I am going to spray the same paint color over the front end (black)
Can I 400grit wetsand and then can I paint over it? (hood,front bumper)

And for the fenders I want to just re-clear coat it
Can I 1000or1200 grit wetsand and then put clear cloat over it?


Also do I need to primer or anything?
or will these steps be good..

thx!

 

are you planning on sealing the bumper and hood before you spray them? sealer is thicker than base coat and helps hide any sanding scratches from prepping. it also helps adhesion. i know of a few painters around my area that have started using 600 on their blend panels, where all you mainly spray is clear. 600 and a grey scotch brite pad for the corners and body lines. but, if you dont feel comfortable with that, the 1000 or 1200 will be fne. but i use the 600 also and have had no issues, besides having to be careful not to go through on you edges .

 

oh I see.. how about for spraying paint over it?

 

You can spray base over 600. You will still have all the chips though. Base does not fill. Even a high build primer most of the time will not fill chips. Even if it does you have to worry about the primer sinking later on. Meaning it would show up eventually down the line as the primer fully cures under the paint. Most good primers do not sink though. The best way to do it is to DA with 220 the chips and then use a high build primer. Sand down the primer with 400 or 600. Anything inbetween there and then shoot your base and clear.

 

thx for the info..

Can I sand 400 and spray base and clear wittthouut PRIMER?

Because 400 get rids of chips.. and it turns white once I sand the chip marks with 400 ..

 

You should read the sticky about repair. The chips need to be repaired then cleaned and primed. Sanding then base/clear would be half ***. If you have a lot of chips and imperfections, as mentioned the most ideal basic steps would be to:

Feather out the chips with 220 DA, then finish w/ 320 DA

Prime

Guide coat then block/ sand and level the primer w/ 500

500 the rest of the parts

No need to color blend black, just panel paint it. If you want to just clear hit it w/ 800 and scuff the edges.

These are basic steps, not an in depth procedure, so grits and technique will vary. Also if you don't repair and prep properly, any poorly repaired areas will really stand out since its black.

 

little bit of chips

 

you can clear over 600, i swear . as far as chips go, you will need to either feather edge them like disease stated or you can wipe in some putty, easysand etc., they make putties that are for filling small chips before basing. you use a razor blade to just wipe it in the chip to fill it. but, sometimes you see it, sometimes you dont. best meathod would be to sand it out, prime, come back the next day and block it out, then paint.

 

Dupont Final Fil works pretty good 2K spot filler. Sand the chip a little to remove any rust/clean it up and smooth it out a little. Clean it, fill it - compress the filler into the chip and the surrounding edges, leave a slight hump to compensate shrinkage when it dries. Once its completely cured smooth it out and feather it into the surface. Keep in mind this black and it may not be perfect once your done.

 

if your really lazy you could puddy over the chips and spray it but thats a very ghetto cheap fast solution, which it seems like you want

 

^^^^

 

so what SHOULD I do ....? whats the non cheap good way.

 

We explained both common methods, sanding-priming and filling w/ spot filler/puddy. Nobody knows your abilities and the exact condition of your car so its up to you, on how to proceed. Your best bet is to do a combination of both so you have primer to level and feather into the surface or just sand then high build and block it.

 

ok.. and if I want to respray only what should I do? and some part re clear only what should I do?
