Gempler's Rust Converter - Quart

This really work great

I used Gempler's rust converter for the first time on some Civil War cannon shot. After 2 coats, the rust was gone and replaced with a nice flat black like the day they came out of the Arsenal. Really great product!!

Easy to apply. Dries in less than an 30 minutes. Can reapply in less than 20 minutes. Two coats does the job, changing the rust to a black coat. The quart will probable do more than 5 sq/ft - double coat. My surface was strong. Badly pitted, rusted through metal would require rebuilding the metal. This only makes the metal paintable. It does not make it stronger. I used a bronze wire brush to prep, blew of the flakes and dust then applied it with a cheap bristle brush. Its thick consistency made it easy to control. Priming was easy. I can't think of anything I did not like about it. I have used similar products over a period of 40 years. This tops my list for rust preventive/sealing products.

Would have gotten 5 stars but I found the gallon jug at a different retailer for less $$$ then what I paid here... but this is an awesome product I highly recommend!

I ordered this on 2018. I was redoing my laundry room sink plumbing from when the house was built in 1956. All the pipes, faucets, etc. were rusted. I followed the instructions on bottle and let it rip. Now I'm writing the real review about the product. I did not paint over the remover. It's on an area that's damp from washing cat dishes everyday. Their is no rust to be found anywhere that this product was used. I'm so happy because I'm getting ready to work on my tractor mower section that has rust from years of parked outside my neighbors house for junk and they gave it to me. It works like new after a new carburetor. Bracket on mower broke off at welds, my fault, so I'm going to rid all the rust away with the awesome product. It should still be good since I never opened bottle since 2018. Wish me luck and I highly recommend this product for simple reason, it works!
