Yes, great article.
They missed Life-Seal, has anyone else had good luck with this product like I have? It seems to embody all the good aspects of silicone sealant plus superior adhesion. Silicone has great adhesion to glass, as you know, because they are distant cousins, but not so much on everything else. Life-Seal seems to have solved this problem. So if I could only have one type of sealant aboard, it would be Life-Seal. Not paintable though...
