Permatex 81756 Rust Dissolver Gel, 8 oz, Red

Very strong solution and works fast.

I have used this on a few things that I had already tried several different rust penetrants on with no success, & this just flat-out WORKS! You have to follow the directions! It will tarnish the metal if you leave it on too long & don't wash it down with water as instructed to do. I now have hope that I can get the front brake lines loose on the Dakota I bought that had apparently spent part of its life up North in the rust belt. HOWEVER, I just can't FATHOM WHY they didn't include a BRUSHED CAP! It's a gel that HAS to be applied with a brush, so why not supply it IN the bottle?! That's a glaring oversight in an otherwise GREAT product! I bought some cheap watercolor paint brushes to use for this.

Good rust remover.

Worked pretty good on my rusted golf cart floor. Easy to apply.

I'm somewhat impressed! I used it on my boat trailer (rusty springs, hubs, etc), and it worked nicely! I "painted" it on with a brush, let it sit for about 30 minutes and then applied another coat, lightly brushing it into the metal to ensure it was in every nook and cranny. After letting it sit for another 30 minutes, I hit everything with the garden hose. Much of the metal was rust free, and what wasn't, I can very easily paint over. Note: It is advertised as a gel, but is more of a thick liquid. Still stuck nicely to wherever I put it.
