Worth the money for every project!
One of the best bathroom caulks on the planet. Very smooth application, easy to control dispensing volume when moving between large and small gaps. The caulk wipes smooth with little effort. This is a caulk that cures quickly (skins in about 5 minutes) so work and smooth as you go. It has an odor during the curing process so ventilate if your working in a confined space like a shower stall. The caulk lasts for years in the bath area with no discoloration. The caulk will also stay usable for up to 6 months after opening as long as the cap is installed.

Good to reseal 3 piece wheels
This is my go to for resealing my 3 piece wheels. I let them sit for 48 hours before I take them to the shop to have the tires put on. This had not let me down yet.

The best silicone made in the world.
Dow 732 is the benchmark of silicone. It meets all the mil spec for silicone. It’s not something that doesn’t meet specs and is packaged for way less money. As a polymer engineer this is the only silicone I will ever use.

Great product
Works as it should. Used it to adhere a stove top to a countertop and it leveled it and held great. I saw a lot of videos of people that say you don't need it when installing a countertop stovetop but I wouldn't do it without it.

Used to seal up a cnc coolant tank, didn't work
I made up a new coolant tank for a little g0704 mill. I cleaned the fresh metaL with acetone to make sure there wasn't any oil residual. I applied the Dow 732, let it cure for a week. I can scratch the silicone off very easily. I don't think the silicone is old since it was smooth and didn't have any lumps in it.

Best Stuff out there
I work at a chemical plant, and this is what they use for just about everything. It's the best stuff I've ever used.

Just what I needed.
This product worked great and is difficult to find in common stores. We use this in my Trade for pitching HEPA filters.
