    My enclosed trailer is starting to leak around the seams when it rains. It looks like a previous owner sealed them with something but the sealant is cracking. Does anyone know what this sealant is? Can I apply something right over the top of the old sealant or do I need to try to remove it? What product works well for this? I bought some flexible window and door caulk at lowes yesterday but now I am not sure if it is the best thing to use.

    I would remove the old stuff, then use Lap sealant. 15788560746624243252038894272816.jpg

    I like dicor if what you have on there now is lap sealant then ya go right over it ofcorse removing it is better but it’s not always possible but a wire wheel is my go to when I have to remove some bad areas

    Sold a horse trailer to a girl once and she took it right to a bed liner place and had them spray the top with white bed liner. Roof didnt leak when I sold it, but I thought that was clever...

    If I'm not mistaken @skyhighZJ said his rv had bedliner on the roof.

    I was looking at doing a roof armor coating but the price was, well, prohibitive. I scrubbed the shit out of it. Cleaned and replaced the dicor lap sealant around all or the fixtures and seams and haven’t had a single issue.

    Lowes has this in stock which looks comparable to the dicor. I think I will try it.

    Just to update...I used a 5 in 1 tool and 3 wire wheels on my angle grinder to remove the old sealer, which was actually applied on top of an even older sealer. The sealer I used is something lowes sells that has RV roofs listed in the product description. It was thick and dry and kind of hard to spread.

    One thing I did learn is you need to put that stuff on a lot thicker then you think they recommend 3 inches wide 1/8 thick I believe I would have just gone right over what you had there just wiped it down with alcohol but I did the same thing as you with my first trailer but I used a razor blade gasket scraped worked pretty well
