The desiccant filter came from Harbor Freight for like $5-$6. We have a local one here.
Yep it's Sherwin Williams auto paint. Originally the guy told me he could sell it for $165/gal and I said NO WAY!! I told him I paid $65/gal for the Iron Gard Yellow and $45/gal for the White.
He wouldn't sell me reducer and hardener for the Iron Gard. When I went back and asked him to cross reference a NAPA reducer # (made by Sherwin Williams), he offered to match the Iron Gard price
.
I don't know if it's the same quality that he told me was $165/gal, but it does set up nice and hard after a couple of days and has a heck of a shine. I probably could have used a fish eye remover as you can see some 'marks' in it when you look close, but it's not for show.
