I have used this on boats and interior post and beam construction. It is wonderful to apply by brush. FYI- I do believe that I am experiencing some compatibility issues with petit brand urethanes. There appears to be a minor bonding issue. Impacts, even minor ones, seem to cause de-lamination.

I used 3 coats on my toe rails & then 5 coats of Interlux Schooner. The old girl looks a lot better now.

Product is so good I us it to seal the guitars I hand make.

I always use 1026 as the first two or three coats on bare wood prior to varnishing. It seals the grain and goes on easily. Then I overcoat with at least 4 coats of varnish. Interlux Schooner is my preference. A capful of Penetrol added to a cup of varnish gives perfect flow out. 1026 skims over in the can after it has been opened. Bloxogen added to the can helps to preserve it. Putting it into a sealed plastic bag should work as well.

I used it to seal the underside of oak plank that will be the bed to a 1955 chevy pick up that I am restoring

Goes on easy dries quickly Sands easily Sealed wood nicely

This made a huge difference in the final results. I sanded the entire boat twice, then one coat of this, then sanded again, then another coat of this, then sanded again. Then varnish/sand/varnish - The results are beautiful. I got TONS of compliments at the wooden boat show. You should feature this stuff in one of your how-to videos, more than just a mention. It is a MUST USE in my opinion.

first time I've used this on this chris craft. we'll see how it works

Two coats of Interprime quickly fills the grain and seals the surface of any wood. Easy to apply and sand, the product is an excellent base for varnish. The product has a nice color and fills and dries quickly. Two top coats of your favorite varnish and your bright work will have that wonderful wet look. Saves on application time and expensive top coat material. This product has gone from a ""boat item"" to being used on all of my wood work projects. My only caution is that once the can is open, even if it is well sealed it will set off in a few days. Use it or loose it.

End grain on hand rails always seems to open and the varnish breaks down long before the rest of the rail. Sealer seems to fill grain and makes a great base for varnish. Will not need as many coats of varnish to get that ""Candy Gloss"" coat. Time will tell if it prolongs the life of the varnish on the end grain.
