Hello to the board....I have been out of rabbits for about 10 years. I am getting back in and was given some old cages that have pretty rusty fronts...and some on the sides, floors are great, double dipped! Just wondering if anyone has ever used a spray galvanizing on old rusty cages! Is it worth the investment! Thinking of trying this stuff; http://www.zoro.com/loctite-cold-galvanizing-compound-gray-15-oz-82039/i/G2417624/?gclid=CJmKoO7Tl8gCFVY0aQodrrQMJA&gclsrc=aw.ds thanks to any who may respond!
