Well I was going to strip my parts down and re-prime but with all the hard to get at areas and number of parts I'm rethinking my approach. I also have a new issue with a couple of parts that have come with the "weld through" primer. I don't know why an inner fender would have weld through primer but that's the way they came. The majority of my parts are from Dynacore and seem to be of good quality. I'd like to just scuff and use two part epoxy before topcoat. Any body have any experience with this approach on both the EDP and Weld Through?
