Dicor 551LSB-1 HAPS-Free NON-Leveling Lap Sealant - 10.3 Oz, Black, Secure, Ideal for RV Roofing, Maintenance, Repair, Appliance Application

Perfect product for resealing our RV roof. Exactly what we needed.

This is one of those “buy it every year without even thinking about it” products—and for good reason. My boyfriend swears by this non-leveling sealant for the camper, and at this point I trust it purely based on his loyalty alone. If something keeps making it back into the cart year after year, you know it’s doing its job. We haven’t used this specific tube yet, but past experience says it holds up, does what it’s supposed to do, and saves us from bigger headaches down the road. Five stars for consistency, reliability, and for keeping the camper in one (non-leaky) pieve.

Item as described, good quality, works good.

I like the product , but the nozzle breaks away from the tube.

Purchased for a friend to repair a small leak in his RV window. So far it has held up during several downpours. I have used it in the past and always have a tube on hand.

I put a StarLink on the roof of my RV. I used this to adhesively bond the mounting bracket to the StarLink and to the roof, as well as to hold the data cable down and seal the hole it routs through.... with the rain and traveling, I can attest that it worked out very well. Update... I have put on a out 10,000 miles now. Nice having full internet/wifi at 70 mph! Note that the only penetration in the roof is a 5/8" hole for the cable. The StarLink is mounted facing forward so at high speed it tends to push the panel into the roof rather than pull it off. I used this as the adhesive to the roof (cleaned the roof with rubbing alcohol first). Got a 3rd party mount, mounted that to done galvanized building plates from ZHonedepot, and bonded that to the roof. I also took a 1" piece of cloth soaked in this, and forced it as a seal around the cable/penetration so that half the cloth is inside and half outside. I have had no leaks, and the panel has not come loose. This is great stuff.

I love Dicor but the shipping didn’t work. It was placed in this large box without anything to keep it from bouncing around. So, the nozzle broke off making it unusable. Amazon offered a full refund so I’m satisfied.

I used this to seal my replacement TV and Cellular antennas to my RV roof, and it works perfectly! Don't be stingy when you lay your bead down. Make sure it's thick and wide before you press your project into it. Then cover the top of the mounting flange with this stuff before packing up your looks. We just had biblical level rains here and my ceilings are dry.

Easy to work with.

Easy to use and does what it’s supposed to do

Purchased to use on my travel trailer in areas that had either sunk or cracked. I cleaned the area well before applying. Happy with the results so that I do not have any leaking.

Fast shipping. Great product. Have always used Dicor products on my rig and very satisfied
