Have a problem

I painted my front grill sometime ago and I guess either the clear wasn't done properly or something an now I have some orange peel coming up, I have some questions about getting rid of it, any help guys, I'll show pics if need be

 

Probably sand and repaint, if you have orange peel.

 

Any specific grit?

 

Also, make sure your paint/thinner mixture is right. That is, if you using a paint gun and not spray paint.

 

Depends on how bad the orange peel is. If it's really bad, start with lower grit (100 or so) and work to a finer paper from there (probably 400 - 600 grit before paint, the finer the better). Spray paints can cover sanding lines left by 200 grit but automotive paint will not.

If the orange peel is fine and only in the finish, wet sand with 400 or 600 grit to basically polish out the orange peel.

 

Do I need to do any buffing?

 

If you are just trying to sand out slight orange peel, 400-600 is too coarse & will burn through into the base coat, unless you are starting over to paint again. To sand slight orange peel, wet sand starting with 1000, then 1500, finish with 2000 or 3000 grit. Then polish with polishing compound to make it shine again. I use Meguiars products. Be careful not to burn through the clear coat layer into the base coat. If you do, you will have to start again with the base coat, followed by clear coat.

 

Do I need to respray the clear coat?

 

I would only if you have heavy orange peel & you have to do a lot of we sanding. Otherwise when the orange peel is gone & pleny of clear coat left, then polish will bring back the shine. You also have to be careful not to use a polish that is too coarse & cuts into the clear cut too deeply.
