"I used it as a paint additive as instructed on the can but was slagged off for doing so by certain forum members who said that paint manufacturers spend a lot of time developing products and if they thought their paint could be improved with additives then they would have done so themselves. It certainly seemed to help maintain the wet edge of the paint in application, whether it has helped to prevent rust I've no idea. \n \n\n\n\t \n \n\n\n\tI personally wouldn't use Owatrol as a rust treatment or as a bare steel primer as I think there are better products on the market. In my mind you either get rid of rust mechanically or get rid of as much as you can and convert the rest. The only paint product I would use directly over any remaining surface rust which can't be removed mechanically or flash rust which has developed overnight is a good two pack epoxy. \n \n"
