Seam and roof sealant

[sides]

What is the best,  A seam, B roof, C window,  sealants. Do not say silicone, it sucks.  Where do buy good sealants and what are the names? Simple question, I  hope to hear a lot of replies.  Thank you.

Dicor Lap Sealant for the roof and seams. Use the self-leveling type on the flat roof and the regular type on vertical seams. Silicone is normally used on windows, but if you don't like that, use Geocel Proflex RV or 3M Body Seam Seal.  Those two are also excellent alternatives for vertical seams.

And EternaBond tape for roof seams.

Also lots of Dicor self leveling and non self leveling.

Like others, Dicor lap sealant and Eternabond tape.  I carry it everywhere and use it more often than I would like.  Never had a failure that was the fault of either of those products, and I've used them hard at times.

Eternabond also sells a sealant. I use that and their tape with good results.
