I have a popup camper with an aluminum roof. There is a seam that runs the length of the camper where two pieces of aluminum meet. There is an piece of trim that covers the seam, but the sealant had failed. I removed the trim, cleaned it and the roof. If I plan to use Liquid Roof on the whole roof, how should I treat the seam (install trim on top of caulk, butyl tape, before reinstalling the trim, after)?
The aluminum roof also has numerous divots/dents from limbs, hickory nuts and hail over the years. Is there something I can use before the Liquid Roof to fill in those dents/divots (i.e. smooth out the roof)?
