Preparation & Application Tips
Preparation is the key to good-looking, long-lasting, results. A properly prepared surface is clean, solid and dry. Do not paint immediately after rain, during foggy weather or when the temperature is below 50 degrees Fahrenheit.
Use a foam roller or firm polyester brush for best results. If spraying, thin with xylene up to 15-20%. Avoid lap marks by not painting in direct sunlight and by coating sections of the surface either down or across hull to natural breaks, maintaining a wet edge.
If your edge begins to dry or you see that you missed a spot and the primer is already setting up, allow it to dry completely before touching up that area.
Do not lather on primer too thickly or you will compromise all flexible adhesion characteristics that make TotalBoat Primer one of the industry's leading one-part undercoats. Dry Film Thickness (DFT) should be 1-2 mils.

Very difficult to work with as it dries very, very quickly. I wish the person I spoke to had told me that. I do not know yet how it will hold up.

Used it for my boat and not impressed at all. Drying time is supposed to be about 3 hrs. When it actually was about 10 minutes! Very difficult to get a good even coat applied.

A few comments, first if you apply in hot HUMID conditions, even watching thickness and application method, make sure it is really, really dry before top coating. It was dry to the touch and to a very light sand, but when top coated with Wet edge the primer spots stayed gummy for days. Wound up sanding right back and starting again, much thinner coats (applied with a foam brush) and drier conditions. But the thinner coats mean it does not cover the TotalFair, which I really like, well at all. I have a white hull and I am working on the 3rd coat of primer and the darkness of the total fair is still not covered. So, not too impressed. Perhaps it works beautifully in a climate controlled shop, but not in my boat shed.
