Sealing Seams

For older campers I have used all the main brand caulks but last February I bought proflex brush able seal and used a small paint brush. This stuff is amazing. Every seam, window frame, running lights, roof and vent seams, screw holes, and even the AC shroud that had cracks. It has been 10 1/2 months since I did the old 98 Lance and seal is strong!! TC has been through some major downpours on road and at campsites and seal is strong with no leaks. Especially around the dreaded front window on Cab over which I detest!!
