Brush Always use a clean brush that is kept specifically for varnishing. Clean brushes before use.

Roller If rolling, use a thin nap roller and "tip-off" with a clean natural bristle brush.

Other Spray pressures listed are recommendations only. The applicator may use any settings which yield the best results for the individual spraying technique and current weather conditions. To enhance appearance of the bare wood and fill porous open grain, apply Interstain according to label directions and allow to dry overnight.

Some Important Points Never leave bare wood exposed for long periods of time as it will absorb moisture. Avoid using Goldspar straight from the can as this will cause it to age prematurely and may introduce contamination to the can. Failure to follow proper dry times carefully will cause improper drying, wrinkling and loss of adhesion. Avoid painting in direct sunlight. Product temperature should be minimum 10 deg C/50 deg F and maximum 29 deg C/85 deg F. Ambient temperature should be minimum 10 deg C/50 deg F and maximum 35 deg C/95 deg F. Substrate temperature should be minimum 10 deg C/50 deg F and maximum 29 deg C/85 deg F.

Compatibility/Substrates Apply to clean, dry, properly prepared surfaces only. Goldspar can be applied over any varnish as long as it is adhered well and has been cleaned and sanded. Do not apply two part varnishes over Goldspar.

Does what it is suppose to do.


If you do your light prep sanding and the weather is right the only thing you have left to worry about is watching for runs on vertical surfaces. But that is true with any varnish.

Easy varnish to work with


This is a slightly odd varnish, in that it looks gray in the can or in your paint-cup. But it goes on clear, as near as I can tell. It's a pleasure to work with. I find it spreads much better than the "Captain's" varnish that I used for many years (Z-spar). I apply it with high-density foam brushes (the ones made by JEN Mfg., and NOT the cheap ones you buy at the big box stores!) and it goes on like a dream. Last year I removed the toerails from my boat (don't ask) and while they were off, I varnished the, with this product, using a Whizz "weenie roller" and then tipping off with a foam brush; results were great.

Excellent Product


Used on top of West System epoxy after cleaning blush and a light sanding (220 grit if I remember). Put a few coats on with another light sanding between each. It worked great, looks great. Doesn't smell near as bad as other varnishes I've used.




Great Product


I applied this product over the West System Epoxy that I first used as a sealer. It looked like a million dollars. It was easy to use, smooth and clear color to make the wood look rich.I am restoring my vintage hydroplane to show and run on the water.
