There are certain applications that Acurglass works well because it flows, such as filling cracks.

For most of my work I prefer two part epoxies that have the consistency of peanut butter.

Marine Tex works well. You can find this in Marine Boating stores.

AcuraGlass gel is good.

I have outstanding success with the Devcon Stainless Steel Putty and Aluminum putty. Once these harden you have to grind them out. Rock hard.

Bisonite works well in certain applications. During its exothermic stage it flows then it thickens. Bisonite is as rock hard as Devcon once it cures.
