100% Silicone Roof Patch Sealant - Complete Waterproofing - Easy Trial or Brush Application - Designed for Your Home, RV, Camper, Trailer, Commercial Building… (2 Gallon, White)

Wanted to update my review on Marlin Roof Flashing Sealant. I applied this around my polycarbonate skylight and new vent fan many months ago. It was simple to apply. It has worked better than any roof sealant to date holding up to brutal sun, hail, pouring rain, bird poo, debris, etc. and no more leaks ever! I used the Black one and after all these months it still looks like new! When it rains hard or I wash the RV the dirt etc. rinses right off the Marlin sealant and leaves no trace! Highly recommend!!!!

UNBELIEVABLE PRODUCT. REALLY STRONG AFTER DRYING AND EASY TO USE.

This roof flashing is Amazing!!! I was only expecting to be able to do all the excrucians of our 28 foot RV with half gallon, but when I finished all of them I still had half the container left so I continued and did the entire outline of the roof 5 inches wide! This product spreads so easy with a paintbrush or spackling tool it’s thick and creamy like soft marshmallow goo but spreads like butter and levels so lovely! The white color is bright silky shiny looking white that is just perfect. It cleans up super simple with soap and water or little mineral spirits in a rag. I got some on my clothes and was able to wipe it all off easy. This is a superior, high quality product. Made in USA and it shows! Thank you to the creator of this product it made my job so easy in like an hour!!

We installed this product two years ago on a specific joint on a steel roof. It leaked the next year. We studied installation videos and realized that the expansion of the joint separated the silicone seal and it leaked. This year we carefully removed the previous repairs, cleaned the joints completely and used a webbing strip and reinstalled the silicone. No leaks so far. It was a lot of work.

This product goes on easier with a roller, i used it with a cloth material for roof patching and it does not want to come off whatsoever. Always remember to prepare surface and clean well, then you will have sucess.
