I have noticed that the caulk on the camper is starting to crack. I have bought a scraper to take the old caulk off. My question is after I scrape the old caulk off, what do I prep the surface with before recaulking? The surface on the 5er is gel coat. I don't want anything too harsh that might damage the gel coat, but at the same time after doing all the work to scrape and recaulk I want it to adhere properly. Using DICOR 551 to recaulk.
Thanks in advance.
