The body is poplar and the neck is maple. Both the body and the neck will be painted at the same time as it is a neck thru guitar. Please advise

Hi all. I have an 80's charvel model 5 that I am bringing back to former glory. I plan to strip the paint off, pull any dents/dings out via the wet rag and soldering iron technique, sand it back and then fill it ready for pre paint base/sealant. The guitar is going to be sprayed with either water based paint or solvent based paint depending on the colour/effect I choose in the end. I need advice on what is the pre paint base/sealant for water based paint? What is the pre paint base/sealant for solvent based paint? Just concerned that there will be reactions that cause a crappy finish if I don't get it spot on.
