I purchased Blue Cortec Brand Rust and corrosion inhibiting bags to protect my moulds. They are 6"x8" Blue, 4 mil thick zip lock. But I had to purchase 1000 bags and have many many left over. I"m selling them for $4.00 for 10 bags plus postage. Email me if you can use some. I work out of town during the week, so be patient with my getting back to you. They are Cortec brand, number VPCI-126, check their website at www.cortecvci.com Reach me at ninemileagency@emerytelcom.net
