rubber spray sealant on roof
Has anyone used a rubberized sealer in an aerosol can to seal up around parts on the roof.

This is my preference, and what I have used for years. I do not recall of going to any RV parts store, or building supply store that did not have it on the shelf. It gets very firm, but remains pliable with your fingernail. This allows flex between two surfaces. It is not easy to remove. I appears to be what was used on my 1988 Bigfoot. You need only put it over the cracks, no need to spread more than 1/2-inch wide.
