A Real Painter Advise

how to sand and prime, and would i need to use bondo filler if i dont have any dents or dings, left fender 95 cavy trying to prep for painting, thanks

why would you need bondo if you dont have dents?

thats what he is asking. no you wouldnt need bondo if you are satisfied with the condition of the metal. bondo is only used to fill in small dents and cracks that dont want to be seen in paint. i dunno about the painting or sanding thing, seeing as how i have never done it, but i do know about the bondo.
