Por15, Eastwood rust encapsulator something else?

Are you going to blast it clean, or just clean it up and paint it? If you blast it, spray it with epoxy primer like PPG DP90LF, let it sit for a day and then spray your color right over the top of....no need to even sand it within that time frame between epoxy and paint. If you're just gonna wire brush it and paint it, just buy black implement paint at Tractor Supply, thin it a little and add the hardener they also sell to go in it...and spray it. POR-15 is a lot more expensive and won't do you any better of a job than the implement paint.
