## Questions & Answers

**Q: Whats the difference between the red and black?**
A: It depends on your application. The black is generally used where oil is present like valve cover gasket. Red is high temperature but not as high as copper. Blue is multipurpose but I wouldn’t use it near heat. Grey is good for water pumps and thermostat. I hope this helps.

**Q: Can this be used as gasket sealer on a cut-to-fit gasket material?**
A: Yes most definitely . Just apply a bead around where needed and give it just a few minutes to kind of set up a little (you can touch it without it sticking) no problem . Makes a clean installation. Thanks for asking

**Q: Is this good fro sealing submersible trailer light lenses? thank you**
A: The most I know, that it could be applied for outside conditions, like onto a window, it’s good. For sealing for it to be submersion I can not say!

**Q: how well do this hold up to atf+4?**
A: That shouldn't be no problem as long as it is fully cured. I wouldn't try plugging a hole or anything like that but it is great.
