Akfix HT300 High Temp Silicone Gasket Maker (2x10.1 fl.oz.) - Red RTV Gasket Sealer, Flexible High Heat Silicone Sealant Up to 600F, Valve Cover Gasket Sealant for Automotive | 2 Pack

I love this stuff.... I use it on just about everything. It does exactly what they say it does and its cheap. Ive had problems with some of their competitors products in the past but never with this stuff..... the tubes also come with a reusable cap which is really nice..... the longest Ive kept a capped opened tube of this stuff laying around was about 6 months and it was still in the same usable condition as the day I opened it. I recommend some disposable gloves and some caution while using it though because that red wants to get on everything and it sticks good as long as the surface isnt wet

No leaks after used for a head gasket sealer on a flat head 6 cylinder engine.

Worked well.

Real good top notch product and you can't beat it you can put it in a cocking gun saves so much time. Barley any smell very durable the application is easy.

Works great, but it's thinner than I thought and can be a bit messy if you're not careful.

Good quality high temp solution,caulk

This is good gasket maker!

It works and am content
