    • works on plexi to steel
Color: Black Style: Compact
i used this to glue a plexi sheet into the back window of a dodge ram. full width, solid sheet. it was soft enough to spread out with a normal culk gun. the bead came out well, stayed proud, and did not sag or drip. the window stuck to it with out any issue and now a couple weeks later - its still solid. no leaks, wind force from driving has no effect. it seems to have bonded very well. ... show more

    • Excellent non-sag RV sealant
Color: White Style: Compact
This stuff is great, but I'm taking a star off because they shipped me Gray and the product description clearly states White. I used it anyway, and that is a seller issue, not a product issue. Although, maybe it is a product issue, since the color is in tiny text on the back side of the tube. I had to search for that to even find it. By then I had already opened the tube seal. ... show more

    • This is the only caulk for trailers.
Color: White Style: Compact
This is the only long-term repair for trailer leaks. Been using this product for 10 years now and have never had a leak on any repair that I have done This is only accomplished after proper preparation getting aluminum shiny clean before application.. I may be crazy but I even use it to caulk my tub. ... show more
