Rain gutters and body seam sealers

Here's the stuff I use.View attachment 1715687447

I bought the 26:1 caulking gun because the tube actually has 2 separate chambers and utilizes a mixing tube. I tried a regular gun, but it is really hard going. Check Evercoat's website. They have other products there as well. I avoided the single stage brush on stuff. Why.....I think 2k is more durable? Who knows. Good luck.

Does it come out kinda transparent blue?
