The U.S. Army bent my brain--if it doesn't move I paint it.
I thin a quart of Rusolteum gloss black in a plastic oil drain pan--get a pair of
rubber gloves and dip my chains in the paint--swirl them around a bit, and hang them up to dry on the A frame I built for my dirt bikes. I paint the hooks
JD green.
The paint chips off with use so when I am painting shovels, grubbing hoes, binders, my dogs (not really) I give the chains a bath.
Probably not the best method, but I get a kick out of it and I think I have new stuff for a while. Controls the buying impulse and I really, really hate rusty anything.
