I was watching a commercial for "mighty putty" (infermercial style product) www.mightyputty.com and they were selling this stuff at 6 tubes for $19.99 (sure shipping is $8.95 but I buy mine online and shipping aint much different). then I realized it looks EXACTLY like my $9 per 4oz stick marineland epoxy from the green outer/white inner that need to be mixed to white right down to the clear tube its packaged in. same claims to what can be done with it. of course the marineland says "non toxic" and the commercial doesn't mention it. I think I've be dubbed! I'm almost positive this is the exact same stuff. anyway to be certain?
these are the warnings for the mighty putty:
COLOR: Disappearing green dye that cures white. WORKING LIFE (min.): 10 SHELF STABILITY: 6 months minimum @ 75°F SHORE D HARDNESS: 75-77 LAP SHEAR TENSILE STRENGTH ON STEEL (1” x 1” x 1/16” LBS.): 700 psi (GBS/GBS) TEMPERATURE LIMITATIONS: Dry: 250°F, Wet: 125°F COVERAGE/LB: 122 sq. in. @ 1/16” CHEMICAL RESISTANCE: Resistant to hydrocarbons, ketones, alcohols, esters, halocarbons, aqueous salt solutions and dilute acids and bases. ELECTRICAL RESISTANCE: 30,000 megohms DIELECTRIC STRENGTH: 300 volts/mil SHRINKAGE: Less than 1% NON-VOLATILE CONTENT: 100% COMPRESSIVE STRENGTH: 12,000 psi FULL CURE: 24 hours Net Wt. 2 oz tubes
WARNING: Potential skin sensitizer. Contains epoxy resins and amine which may cause irritation to sensitive skin. Wash hands with soap and water after use. Use gloves if you find skin sensitivity. Eye irritant, in case of eye contact, flush with water. Contact physician. May be harmful if swallowed. KEEP OUT OF REACH OF CHILDREN. SEE MATERIAL SAFETY DATA SHEET FOR COMPLETE INFORMATION
I bet the MSDS is the same for both

What did you decide after reading the MSDS for this stuff? If you can't flush it down the sewer, I'm don't think I would want to put it in MY tank. I'm interested in YOUR thoughts on this.
