TotalBoat Topside Primer can be used as a great tie-coat primer, but should not be used as a solvent barrier when it comes to applying a 2-part paint over it. Two-part paints usually contain much stronger solvents, this is why they generally should not be applied over 1-part products. In this case, TotalBoat Topside Primer should not be considered a solvent barrier, just a tie-coat type primer to promote good adhesion.
Can TotalBoat Topside Primer be used over a 1-part paint as a tie coat before applying a 2-part paint?
