You dont wanna use that laquer primer over any bare metal. Like someone already said you need to etch the bare spots. If the whole truck is metal Id shoot epoxy on it. If you use epoxy it willl be protected and when its time for body work you just sand it and and put your filler right on top of it. What I did on mine was strip to bare metal, rough in all major bodywork with 80 grit, mix my epoxy as a sealer and get a nice coat on everything. Now when Im ready to paint I will just sand all the epoxy with like 180, llay a few good coats of slick sand sprayable polyester bodyfiller, block that out with 180, fix any minor imperfection that shows up in blocking, lay a few more coats of slicksand, block with 320, seal, paint.
