not reading any replies, but always remember, every topcoat requires/wants a certain etch to grip...... no product likes to just "overcoat" the previous, other than paint over a sealer primer.. and that is the exception to the rule in bodywork... if you are priming for bedliner, first you are sidestepping an important process in topcoating over a primer...
but I get it, 97% of society doesn't really care about the actual best way to protect a surface and goes right to bedliner over a primer or raw steel..... (than cries when chit fails
)just keep in mind, all coatings stick best to a certain grit, bedliner, being as thick as it is, will suck right into the nastiest cut it can.... primer, than 180ish will do well... the nastiest cut you can do, without removing all the primer is best..
from your average bodyman...
