In my experience, yes, your going to have to sand your sealer. I dont think you need to go crazy with it but you should do something to give the next coat of whatever something to bite onto. I would NOT spray adhesion promoter on it. Adhesion promoter for plastic is some nasty stuff. I think it would just melt your sealer and make a big mess.
