^^^ he's sanding his wiper arms. 320 with a block or by hand is fine. if your worried, do 320 wet. remember he's trynig to get all the paint off the arms.


honura-- go in the diy section, there's a how to on painting your headlight housing and talks about "baking" your headlights to soften the sealant. i did it and opened up my stock lights to take out all the amber peices.

 

^^you don't need to get all the paint off the arms. Just sand until the existing paint is a lighter shade. All you need to do is sand so you'll get a tooth for the paint to stick to. I don't know why EVERYBODY in here thinks you have to sand down to bare plastic/metal. If you spend more than 20 minutes sanding both Arms...you've sanded too much.



I work at a body shop and do all the sanding (it's just my dad and me). So I have experience in sanding car parts.

 

we used a hairdryer, lol
