I LOVE this stuff. I seal a lot of automotive areas prone to water intrusion. Never let me down. Stay flexible and strong adhesion.

Sceller les fenêtres d'un vr en fibre de verre. Le produit est parfait, mais j'ai dû retarder la fin de mes travaux parce qu'il est arrivé 3 jours plus tard que prévu. Sinon très satisfaites!

Excellent improvement over marine silicone. This is flexible and superior to marine silicone and is still temporary versus the 5200 option. Would buy again? Black color needed to match my boat gel coat.

a thin waterproofing layer didn't cure in 2 days and is still tacky. A larger amount of product does not cure inside at all. It feels like the product is either bad quality or was not properly stored and lost its qualities. Update: read Home Depot reviews for this product. Most reviews say the same as per the above - bad product, does not cure.
