We have used Huber liquid flash to cover all of our window and door openings. Still as a belt and suspenders approach I would led like to have a sill pan. I’ve looked at jamsill but we are worried about the pvc cement interacting with the liquid flash and our huber rep couldn’t tell us if this is ok. Of course he suggested their flex tape. Does anybody have any thoughts or recommendations? I do not believe they sloped the openings. Would I be ok with just a foam backer rod?
