Deckster is sold by sunbrite
www.sunbritesupply.com they also sell Ready Seal.
Or, for Ready Seal, call Mr. Peirce Fitchett at 410-381-8400 I'm sure he'd be glad to help.
Spend some time doing searches on this board under "Ready Seal" there will be alot of info, but you should find the answers to alot of your questions.
