A friend has suggested using the same epoxy
product that is used in spraying PU truck bedliners (such as Rhino Liner) as a less expensive alternative to VC Tar. He says it''s substantially the same as VC Tar. I checked the wsebsite for Mar Hyde, which I believe is a similar product, and it only costs about $54. a gallon, even without a discount, which is a whole lot less than VC Tar.
Has anyone ever tried it? Is it a good idea, or an invitation to a bad bottom job?
