This product works
This stuff really works. My wife purchased a vintage camper that was leaking from the marker lights and front window. Let's just say, NOT ANYMORE!! This sealant works GREAT!! Definitely recommend this product for any sealant needs. 👍🏻👍🏻

This is great stuff - Apply with care
I used this to reseal the inner framing of a cargo van to the shell where the original manufacture bonding broke away. I left the original foam looking bonding in place. It was still firmly attached to the framing. The Sikaflex bonded to both the original foam and the the steel van shell. It helped reduce some of the vibration and noise. I allowed 6-7 days cure time. BE CAREFUL TO GET AS LITTLE ON YOU HANDS AS POSSIBLE. Clean it off your skin as soon a possible. Even after half an hour or so it is hard to remove and remain on your hands for a week or so.This a high quality strong elastic sealer adhesive. Once dry and cured its strong. Relatively low odor. Highly recommend.

Great product for restoring my old camper
Applies nicely with no sag. I used it for all of my penetrations for various camper component replacements (microwave vent, windows, etc.). I did not use this on the roof though, I used Dicor.

Works great!
Works just as described, used it to fill leak gaps in cinderblock wall, went on well and the paint I applied after it dried went on well as well. Solid product, would buy again.

Hard to Dispense and Messy !!
First thing I absolutely hated about this product is that it is nearly impossible to dispense it from a caulking gun without using both hands to squeeze the trigger. This makes for a messy job no matter how hard you tried not to. DO NOT get this stuff on your skin or clothing. I ruined my shirt but it was a work shirt anyway. Stains your hands black and is nearly impossible to get off even after 4 days of trying. Time will tell if it sealed up the RV window well or not.Do yourself a favor and buy something easier to use. A 10 to 15 minute job ended up taking and hour and a half to finish. Making the hole in the end of the caulk tube didn't help at all. I will not be a repeat buyer of this product.
