[QUOTE=kjoh75;194402]Do I need any prep work to insure a good stick?
No, Prep is not required; the Dicor is pretty sticky.
A wipe with an Acetone dampened rag will soften really dry sealant and can help ensure a great bond, but BE CAREFUL. Wear RUBBER gloves (nitrile or latex will melt). If you kick open an open can you will be buying a new roof.
If have access to Eternabond Primer spray you could use that. But if you have that; I would finish the job with Eternabond seam sealer.
