Q. I've been using POR-15 Rust Preventive Paint for years. Can I use BLACKCOTE instead and get the same rust protection?

A. No. You can use BLACKCOTE on bare steel and get good protection, but it is not comparable to POR-15 Rust Preventive Paint, which penetrates into the pores of the metal and chemically bonds with the surface. Use BLACKCOTE as a topcoat OVER POR-15 to get the best possible rust protection.
 

Q.  I've put BLACKCOTE on bare steel and have gotten a terrific bond. It sure looks as good as a POR-15 coating on bare metal or steel. Isn't is just possible you're only trying to sell me another can of paint?

A. Absolutely not! Side-by-side panels were tested under a variety of conditions, and the POR-15 coating was shown to be clearly superior in preventing oxidation and corrosion. Try it yourself and you'll see. Though BLACKCOTE will easily out-perform other coatings on bare steel, it's greatest value and best use is as a topcoat over POR-15 Rust Preventive Paint.
 

Q. How does BLACKCOTE work over other painted surfaces?

A. Very, very well. There are many occasions when you want corrosion protection over a painted surface and you can't remove the old paint. Simply clean that surface with  Marine Clean to remove grease, wax, oil, silicon etc., scuff lightly, then topcoat  with BLACKCOTE. By the way, other colors (white, gray) will be available in the near future.
 

Q. Is BLACKCOTE the "perfect" topcoat, or does it have drawbacks I should know about?

A. Unfortunately, nothing is perfect in this world, not even BLACKCOTE! Like POR-15, it won't come off your hands if you let it dry; it will harden in the can if you leave the lid off and dip your brush directly in the can; it may occasionally have some tiny imperfections in its finish, so we can't call it a perfect cosmetic coating; and finally, it is certainly not inexpensive. It's very difficult to make, and the base resins are very expensive, but we've never let cost stop us from making the best coatings money can buy. BLACKCOTE is one of those coatings.
