I would give Barry at SPI a call and see what he recommends, if anything. You may be able to find what you're looking for on their forum also. SPI makes an adhesion promoter as well. www.spiuserforum.com

I'd do just as fenderman said go to their site register find the correct forum and ask the question .I'd be suprised if you don't have a answer from Barry K (owner) within a couple of hours!
