Will using a deglosser then Kilz2 before painting be enough? (latex over oil based for indoor trim and doors)
Or is it absolutely necessary to sand and TSP? or oil based Kilz or bonding primer??
The guy at the paint counter said the primer already in my paint will be enough to paint over oil-based paint, but I think he is bonkers. If he's not crazy, please let me know because I'd love to save the work and money!
