## Description

Flex Seal Spray Rubber Sealant Coating 14-Oz Gray 2 Pack

Review: Seems to work - Basic product seems to work. Doing a test right now. VERY VERY EXPENSIVE.
Review: Misleading commercials - Really on the fence with this product. Sounds remarkable in theory. I'll start by saying I have a 2001 tacoma 1st gen that has the typical leak under the dash. After hours of research I found the general area that I needed to address. Looked like two pieces of sheet metal pushed together with no water proofing. Instead of just relying on this product I also bought an automative polyurethane sealer that I used first. I knew it would be a messy fix and the flex seal was to help fill in the imperfections and more closely match the paint color as the sealant was black. My first issue with flex seal was, 1. it didn't spray straight so I had to do a test shot before actually using each time else it went the wrong direction and created a mess. 2. no matter if I went light coat or heavy coat, it still never seems to dry very well. I'm on day 6 and parts of it are still tacky. I live in a very humid area at 90+ % most summer days. I suspect that has a tremendous amount to do with it. But with commercials where they spray this on a leak and it seals nearly instantaneously, needless to say I'm disappointed that it's taking this long. I decided to try putting a fan on it and at this time that's been nearly 12 hours. I haven't checked today but crossed fingers.

## Questions & Answers

**Q: Will it stick to outdoor wood and is it paintable?**
A: I believe it would stick to wood outdoors.  I can't verify that it can be painted as I've never tried to paint it.

**Q: Would this work on an exterior chimney crown?**
A: It worked on a brick in my kitchen so yes it would however you might want to try the Paste version as opposed to the spray. 
The stuff is wonderful. No house should be without it.

**Q: Will this product break down the composition of styrofoam?**
A: Hey there. We don't recommend using Flex Seal Spray on a styrofoam surface as the spray will cause the styrofoam to melt when it comes in contact with the spray.

**Q: Does come with texture?  I want to use it the floor of a motorcycle trailer**
A: It has no texture.
