zadam123, k cause when I talked to the shop here, they said that if it doesn't adhere properly then it can actually start to chip off on the edges. (ie: the corners of our cladding) Thats why they said I would have to figure out a good way to prime it. As for timing, I wasn't to sure because they said I'd have to wait a few hours once it was done before putting the cladding back on to give it time to set and dry. Maybe they are being overly cautious or somthing.

DragonBob, did you end up priming your cladding in any way? Or did they just spray it right on with no real prep-work?
