Has anyone had the opportunity to use and compare the following silicone sealants?
Some better than others? Failures? Recommendations?
  • GE Construction Sealant SCS1200 (may be too soft)
  • GE-012A (GE 1 blue tube. Used to say "safe for aquarium use" years ago).
  • Ge RTV 108
  • GE IS808
  • All Glass (AGA)
  • Permatex 16B
  • CRL 99AS
  • Perennator AQ201
  • Perrenator V43-5
  • Perennator 788
  • Dow Corning 791
  • Wacker Elastosil 4300 (same as Elastosil 121)
  • Perfecto
  • Dap
Supposedly GE is making a lot of this stuff according to other forums, including AGA.

The Wacker (pronounced "vacker) stuff is supposed to be outstanding but is not available in retail anymore, at least not in the states. Too bad because I scored one cartridge in black and I needed a few more to finish my project.

Perennator is German like Wacker and is available in the states but is expensive. I hear it too is a very good product.

I've used the DAP silicone for all 3 tanks and the w/d I built over the last few months. It is very easy to work with and I haven't had a problem with it yet. Unfortunately, I don't have any info for long term.

Thanx. How big were the tanks and did the silicone come in the caulking gun size or the small tube?

I resealed a 30 gallon Hex, a 55 gallon rectangle, a 55 gallon sump, and a 180 gallon tank. They were 10 oz caulking gun size.

Thanx. It never occurred to me to check McMaster.

Supposedly the DC 732 and the GE108 are the same, according to the specs.(NSF, food contact, UL, etc). I never heard of the DC832 but I'll check it out.

Is there a specific number on the GE Construction Sealant?

Hey Buckdog

I have tanks made with Dow 999-A Silicone available in Aussie, some now over 12 years old. A friend has been using Dow 999-A Silicone for more than 15 years.
