Will it fix a leak on the roof of my RV in the rain

Many people have had success using Flex Tape to repair the roof of their RV in the rain.

Can the 8" tape be cut in half to use?

Many people have found great success at cutting Flex Tape to a desired size. Leave the backing on tape and cut to desired dimension. Use high quality scissors or razor blade when cutting. We do offer a 4" x 5' tape as well.

Would this work on a hole I have in my 96 gallon trash can lid that has hail damage?

It sticks pretty well. Its like ducktape with silicone on the back. If its just to cover then maybe. If its to be sealed from water then no. If the holes are small it might be worth a try

will it stick to painted gutter down spout?

Common Flex Tape Applications: Leaky roofs and ceilings Damaged gutters and down spouts Boats, kayaks, personal watercrafts, canoes, and other outdoor equipment repairs Repairs for mobile homes, RVs and campers Leaky PVC and plumbing pipes Sprinkler system, pool, and spa leaks and repairs Patch and seal windows, doors, walls, seams, and vents Repair air ducts and HVAC systems DIY projects And much more!
