  • Easy to use and effective
Number of Items: 1
I purchased this product to seal a new vent cover on my rv. The sealant is easy to use, spreads well, forms a good seal and the container held enough sealant to cover over other small areas on the rv's roof that needed refreshing.

  • Black silicon
Number of Items: 1
The usual caulk on my trailer, for whatever reason, has cracked and dried out. The manufacturer could used better material, but I suppose that would be too expensive. I like using silicone. It flows and shapes easily, and it lasts a long time after it's put into place. This is going to replace some old original caulking that failed and let in water around the slide. ... show more

  • Worked like a charm.
Number of Items: 1
I have some bronze aluminum frame windows and panels on a greenhouse in need of resealing. I used clear before but it just looked hokey. I removed the bad weathered caulk and used this WELLUCK Black Silicone Caulk. Went on smoothly and actually made an older greenhouse look new again. After a couple of days I set the sprinkler to it and no leaks. The tube covered a lot of territory but needed an additional tube. I personally think its a good value for a good product. ... show more

  • Decent Black Caulk
Number of Items: 1
I ordered this product to use in the storage area of my fifth wheel camper. From the factory they used black silicone to seal cracks between the walls and floor in the storage area but with typical RV industry craftsmanship, they did a horrible job. So I got this to finish the job they never did. This black silicone caulk works like most others do. It adhered well and worked well. It dries to tack free in about 20-30 minutes. I was happy with the results. Quality seems very good and the price was average earning this a 5 star rating from me. ... show more

This caulk is a little pricy. Easy to apply. The actual test will be how long it lasts. Time will tell

  • Its silicone in a tube!
Number of Items: 1
I do not know that there is any difference in 100% silicone, I have never seen any difference besides price. Latex on the other hand is different. This worked just as good as any other silicone I have used at a reasonable price as it has really gone up.
