Best sealant for use on corner trim?

[wmuav8tor]

I totally took off the corner trim to fix a leak, I have put down that Dicor seal-tight tape and am now ready to put the trim back on.

Sealants I have at home are Red Devil butyl sealant, dicor non sag sealant, proflex RV sealant, and butyl tape. I’ve watched the videos on YouTube of Mark Polk putting a corner back together but he doesn’t say what he uses to seal it (he used some sort of caulk)

Thanks!

Proflex.

This is the stuff they recommend..

Akfix AMS55 All Bond High Tack,... https://www.amazon.com/dp/B01BY6E7IY?ref=yo_pop_ma_swf

I bought some. It's great stuff. Works well. It's pretty thick. It's supposed to go on under the corner moldings and squeeze out. That'll ensure the best seal.

I laid a bead of pro-flex over it in the corner on the outside after a few days.

007matman, That stuff you link is a adhesive, not the MS All Bond Universal stuff that Dicor recommends
