Even after storing it unopened for years, I could still apply it with good results!
UPDATE: the original tube that I had opened earlier this year dried a little too much to flow out, so I ordered a couple more tubes to reseal the sidewall to roof seam. It really applied very nicely and with a little soap on my finger my job looks professional. AND it was on sale! Photo is of current sidewall to roof seam reseal. Original order July 21, 2024 This is the recommended sealant for apply to the sides of RVs since it does not run. It stays where you apply it even upside down if you need to. It is nice and white which matches the color of my motorhome. I received this sealant about 2 years ago and finally had to use it today June 14, 2026. It might have been stiff due to it being "aged. It was too thick & stiff to come through its nozzle so I cut the nozzle down and used my caulk gun to push it out onto my gloved finger. I applied it that way forcing it into the cleaned areas I wanted to seal. It sticks very well to my motorhome side and I troweled it with gloved fingers. I was able to really make it look very smooth using some soapy water on my fingers. I wonder how it would have flowed if I used it when I first got it but I was still able to use it after 2 years unopened. I like it!

Best sealant for your RV!
Absolutely the best. Not cheap. Applies easily. Two kinds of consistency: a traditional viscosity (like house caulk) and a thinner self-leveling type. Not cheap but worthwhile due to its durability! Second year & no problems!

Love dicor products
I always use dicor on any camper I have worked on and their products are consistently dependable. No leakage amd extremely durable. Can be messy if you aren't careful when applying.

Great edge sealant for trailer roof
Used this on the roof edge of my trailer where rubber meets aluminum/fiberglass with great success. It is not self leveling, so there is no concern with dripping. This an elastomeric product, so once cured, it will still flex with any movement. I live in a Northern clement that sees drastic temp fluctuations and I have yet to see any shrinkage cracks. It is a sticky product, and does not layout like a silicone, so take care when applying. (bring lots of paper towel.) Great product.

The name earns it popularity.
I used this for a 1995 RoadTrek RV repair I did, as well as sealing up the roof trim and window trims that have gaps in them. It seems to stay "tacky" for quite some time so avoid touching it but for sure no water getting through it. Don't cheap out on your repairs with silicone or caulking.

Great product
This stuff worked great, better than the original that was on my camper. Super playable, giving a four star due to the fact I got half way through putting it on my camper and came across a part of the tube that chunky and dried out. Lost about 1/4 of the tube but was still able to finish with what was left.
