The best thing you can purchase for you aquarium. After losing half of my fish to an ammonia spike, this is the only product that detoxified the ammonia and brought my nitrite and nitrate levels to almost zero.

I ordered this product from Amazon to fix a crack in the steering wheel of a classic Cadillac that I own. I am no Renoir, so I did not do a great job of matching the color (light green, which meant I had to mix blue and yellow) but it was close enough. The stuff worked great. It sealed the crack and looks like it will last.
