PRODUCT DESCRIPTION

Stirling Silver is a permanent silver coating developed for application over painted and unpainted surfaces.

* We suggest that if POR-15 has been left for a period of time longer that 48 hours, that a light scuff should be applied over the surface with a fine grit sandpaper or course scouring pad to provide a tooth for ensured adhesion of this topcoat.

QUESTIONS AND ANSWERS

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

No. You can use Stirling Silver on bare steel and get good protection, but it isn't comparable to POR-15 Rust Preventive Paint, which penetrates into the pores of the metal and chemically bonds with the surface.

Use Stirling Silver as a topcoat over POR-15 to get the best possible rust protection.

I've put Stirling Silver 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 it just possible you're only trying to sell me another can of paint?

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 Stirling Silver 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.

How does Stirling Silver work over other painted surfaces?

Very, very well. There are many jobs 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 Stirling Silver.

Is Stirling Silver the "perfect" topcoat, or does it have drawbacks I should know about?

Unfortunately, nothing is perfect in this world, not even Stirling Silver! Like POR-15, it won't come off your hands if you let it dry; it'll 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. Stirling Silver is one of those coatings.

A medium gloss, non-UV sensitive silver topcoat, very tough, non-porous, and flexible. Excellent over POR-15 and other coatings as well. Will not crack, chip, or peel. Impervious to salt, salt spray, and most chemicals and acids.
