I have read everywhere that new sealant does not adhear to old sealant. But does this apply to sealant that has JUST dried. 2 days ago will be 48 hours of drying of my sealant. Used "marineland aquarium sealant" on my 55 gallon. had a small pinhole leak so i stripped all corners with razor, completely clean but without dismantaling the panes. I resealed them and now notice my sealant is not extending as far as the original sealant was.... I did do a bead about the size of a pen or so then pushed in with finger to smooth it out. but I remember the old stuff extending from the corner about 1.5 cm. Now my new sealant job only extends maybe a cm... So should I put a bead on each horizontal edge and extend it slightly? Or leave it?
Everyone comments not to put new on old but seems as though pinhole leaks are often remedied this way? And what if my "old sealant" is a day or two old?
I know I can test it out, but just cannot have 55 gallons fail 2 months down the road in my house
