Footloose is being soda blasted this week. The plan is to apply VC17. I would like some input on barrier coating. There has never been any barrier coat on this boat. I am very sure that no prep was ever done before the PO applied the initial bottom paint as where it has peeled the gel coat shines. I know that I need to apply at least one coat of Interprotect as a primer. Would others go ahead and apply a full barrier coating of 3-4 more coats or just the one? I should add that the boat has no blisters and is on the hard more than in the water due to the short northern sailing season and is in fresh water. Thanks!
