I will be repainting the interior of my truck cab. There are some spots i need to bring down to bare steal but the rest of the paint is in perfect shape. Should I just spot prime the bare steal with epoxy and then use a primer surfacer on the entire cab, then basecoat, then clear? Other than scuffing the clear coat that already exists, would my process i mentioned above work? Or should I bring everything down to bare metal? Or sand all the way through the clear and basecoat?
You can certainly sand to bare metal and scuff existing clear. Once you are ready for paint you could use our Epoxy primer over everything to seal it all in. From here you can either go into a primer surfacer to block the surface or right to paint if you are happy with the outcome when looking down the panel after Epoxy. This process would save you time from stripping everything to bare metal.
