I thought about both Eastwoods and POR15 for my frame, but if your frame is clean with no rust after sandblasting, then just buy some tractor paint and brush it on. It will get the job done, and is only $10 for a gallon. More than enough. That is what I'm planning for my frame. I have friends that have used POR15, and said that it only works good on parts that are rusted.
