epoxy primer??

Go to autobody tool mart and get the kirker epoxy primer. Its good stuff and reasonably priced. Strip the car down to bare metal, coat it with epoxy primer and that will help prevent rust. Make sure you do all of the knocking out of big dents first or get it close when its stripped. Scuff it real good, do your filling, go over with filler primer or featherfill which is what i like to use, block out with 180 and repeat with the filler prime until body is nice and all sand scratches are for the most part gone before really perfecting things. They are a good company to buy stuff from. Matter of fact im calling them right now because i need some stuff that i just remembered.
