So I re sealed with lap sealant July 2023 put it camper up for winter in mid sept with cover and uncover this march 2024 and found the new sealant has cracks what the heck happened every inch of new sealant did this
Yea fake Chinese lap sealant, next time call a dealership and ask what their technicians use. Or go to a hardware store that has a known good lap sealant. You got scammed by Amazon for sure.
Use dicor. It’s like the rotisserie oven. You set it and forget it. That’s a lot of scraping ahead there.
Do you know what type of lap sealant was applied?
It looks like the wrong kind of sealant. I used some self leveling dicor to secure some cables and other areas on my roof and the section that was poured over the cable is broken from the roof. I used their non leveling sealant as recommended for seals and it cracked after a couple months so I had to redo it. Some brands just don’t have enough flexibility but yours looks like a combo heat cold expansion shrinking issue ??
I went on a limb and went with this brand the Amazon reviews said it was better than dicor that’s a big negative this is the brand I used
Wow not even a year. I had to touch op the sealant on my new trailer. I shopped amazon, but decided to pay the small premium at a local RV shop.
