I used it as a sealant on the roof of our Sprinter van to seal the gasket of our MaxxAir fan.

I used this product to reseal windows, joints and lights on my motor home. The price and availability was the best on the internet!

I used it to seal floor hatches and seal the console to the deck. It was easy to work, good results.

I used this product on a boat project, I took an old boat 79, and rebuilt it, this product was very usefull in filling the multitude of holes that various owners had put in the boat, it worked very well for use with fasteners of different kinds,to seal them from leaking it covered well with paint. It is a bit messy to use and caution should be used when using it, to keep from getting it in places you do not want it. It cures quckly, and can be sanded to some extent, not recomended for a dent filler or anything like that.

Choose this from long list of caulks available based on price & durability yet removable.

An excellent, easy to use product. Jamestown should use the correct illustration for the 3 oz. tube. A 10 oz. cartridge is shown. Otherwise, an excellent product.

The website illustration is a 10 oz. cartridge suitable for a caulking gun - which I thought I was purchasing. In very small print it says that one is purchasing a 3 oz. tube. Very misleading and should be corrected.

Tried both 4200 and 4000 for deck hardware/trim. 4000 stays white and is easier to clean up.
