Momentive RTV103 One Part Silicone Sealant, 2.8 Ounce Tube, Black Momentive

This is the same product that many of the aquarium builders use.This is an adhesive, which has a much higher tinsel strength and adhesion strength than the average sealant you get at the pet store.The working time is around 12 minutes. You need to plan out your assembly and go through a dry run or two before actually attempting to put it together for real.The tube was well within date, it was only a couple months old when i got it.If you are doing a tank bigger than 5 gallons, consider the calking tube. This is not the easiest to use to lay down a long even thin bead and keep it smooth and straight. It takes a decent amount of pressure with a thinner bead, you may run into hand fatigue by the time you are finishing up.

Just what I needed for some patio furniture touch up.

Excellent product, but the tube broke open on the end and made a big mess. I ended up throwing it away.

Instead of replacing the shadow line trim, used this product to fill the gaps between the shadow line trim and the glass. Saved hundred of dollars vs. replacement parts.

Purchased RTV103, 2.8 Oz tube, bottom of tube blew out first minor squeeze, of course I'd already cut the stem, leaving most of the tube all over my hands. What little silicone I managed to get where I needed it worked just fine. Will NEVER purchase this brand again.
