I agree with TechNova. The red stuff that comes in a tube with no hardner is no good. It will shrink back and after you paint the car you will be able to see the scratches, pinholes, etc.
Polyester putty is the way to go for filling minor imperfections like pinholes in bodyfiller and sanding scratches. I would not use it for filling chips, I would sand chips out. This putty is designed to be used a very thin coat over bodyfiller or metal but only if the imperfection is very shallow. Do not use this product as a bodyfiller, use "bondo".
Body filler, "bondo" is designed for imperfections that are larger in size and slightly deeper but again is not to cover a dent and should not be more than about 1/8 of an inch or you will have big problems later on or when she leans up against your ride. Spend the extra time and straiten the sheetmetal, don't be lazy anyone can do it if they put in the effort. Buy a book, go to school for it, or get a job as a bodyman's helper.
