I don't know about "Mad Dog" but we have used several primers that do just that. PPG makes a product nationally available called "REZ Permanizer Plus" that I specify on spongy, weathered wood. In my opinion it is a better preservation answer than sanding to sound wood, or replacement of the member, either of which would be recommended by most paint manufacturers. Without removing the deteriorated wood fibers a typical primer – latex or alkyd – will only give the topcoat a few years before it fails. The penetrating nature of a remedial primer provides a good sound base for paint.

The painter for a historic house in Baltimore has proposed using Mad Dog Primer. He described the product as a combination paint and glue that is good for bonding to layers of old paint. This is a new product for me - any recommendations pro or con?
