Keystone RV Forums - View Single Post - 2018 Cougar Half Ton Front Storage Door Damage

It appears (from what I found at Trekwood website) that Keystone uses Tremco (TremPro) 645 which is listed as a silicone sealant / adhesive. Can anyone confirm this is the correct one I should use? Or should I use butyl caulk? (Also going to use butyl tape on back of door BTW).

Wow- Never realized it would be so hard to figure this one out. So much information on the internet and no clear answers!

Thanks for your help!
