well, took off my sidemolding and i wanna fill the holes, how would i do that to make it last? also, the previous owner of the car did a sloppy job primering it and i wanted to know what i could use to remove some primer paint from certain plastic areas that are covered with it

 

you tack weld the holes for the best and long lasting results.
Or if you wanna go cheap you can get tigns like JB weld or duramix and paste it on and fiberglass resien over it.
My friend used JB weld and its holding up great

then again im not a autobody pro

Dont know what you can use to remove the paint.

 

alrite, thanks
