Alright y'all, so I'm closing in on finishing my rear quarter panels and will migrate up to the cowl shoulders soon. I'm trying to look forward to the future as it pertains to under-body protection and coatings. Currently, I have an entirely new (trunk, floor, firewall) sheet metal built car. It still has its EDP coating on it. I am planning on putting it on a rotisserie (or building one out of wood google: tip-over-jig) so I can gain better access to the bottom of the car, which is why I need to finish the QPs and firewall to put it on a rotisserie.
I'm guessing I should wire wheel the entire bottom to get the EDP coating off or should I use a good aircraft paint stripper? I'm trying to figure out what coating I should reapply over the top of bare metal to provide good adhesion for a bed-liner top coat (if you want to try to talk me out of going the bed-liner coating route I'm all ears as I'm not 100% sold on it; then again I'm not building a show car...).
For my DTM process I was thinking a catalyzed epoxy primer (I'm guessing 2 coats so around a gallon?), then seam sealer (either spreadable or in a tube; again, change my mind if you have suggestions...), then a top coat of something good like a POR Bed-Liner or something similar. (Again, I don't care if the bottom of the car is black or the base-coat; frankly this thing just needs to not rust). I plan on spraying the bed-liner with a bed-liner shutz gun so it will go on thick with a somewhat textured surface. Which brings up a new can of worms; textured or not? I've heard textured will hold water. I don't plan on ever driving in the rain and it will live in my garage, if that matters
As a side note I've heard terrible stories about bed-liner coatings, from de-lamination to flaking to chipping. Do they make a catalyzed harden bed-liner? Most of the ones I've seen are single stage water-based stuff, which means you cannot go DTM with it.
Again, any suggestions and pictures of your stuff can help.
