Rain gutters and body seam sealers

Do you know the name of the 2 part bead? I have read that the 2 part is better for external applications but not sure which one to get. Don't mind paying a little more if it's going to last. Don't want to be doing all this work only to have it shrink and crack in a couple years.

It will be getting applied over epoxy primer. Inside I plan to use the regular brush on seam sealer, but want the better quality stuff for the outside where it can be seen.

Here's the stuff I use. images_ePIM_original_100822_MAXIMOEMBead_Cart_WEB_w400_q75.jpg

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.
