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

Dicor is the only lap sealant I use on the roof of my RV. It is a well known and reputable brand and I have never had any issues with application or failure. It works well on the roof of my Crossroads RV and the quality is hard to beat. It applies easy over the old Dicor and settles well into all the cracks and imperfections. The new white looks good and dries quickly and I have even applied while it was sprinkling rain

The product arrived but whoever put the caulk tube in the box smashed in down and broke the tip off the tub. It was almost unusable to usehowever I made it work with much difficulty. The product itself is awesome and sealed my RV roof from leaks.

Works well on campers because it’s flexible I love it

Works well and is a well known sealant. Easy to use . Make sure you prep surface properly. One tube doesn't go far so order more than you think.

Works Great, as advertised.

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.

Product works as advertised. I purchased this after viewing an online video for repairing a broken vent cover on our RV roof. I used the self-leveling sealant to seal around the edges of the newly-installed cover, and after a couple of days, I inspected the work and the sealant had leveled out as promised. I ordered another tube just to have one on hand for the next repair job. Definitely recommend.

It's amazing, went cheaper stuff last year and ended up with leaks.Never again I am back to using this know it works good!
