[VAC] Re: Tung oil - how about spar varnish?

[JSmith1805@xxxxxxx]

Most of the so called oil finishes are nothing more than a watered down 
polyurethane varnish and oil mix. we did a sail boat interior with pure tung 
oil at the customers instance over our objections and it as we told him it 
stunk for a long time. 
the difference between spar varnish and any other varnish is that spar 
varnish has a UV screen in it. the oil finish that i have used for many years 
is as follows .
11/2 parts polyurethane varnish(pefer gloss)
2 parts boiled linseed oil. 
3 parts turpine. (or enough to thin to a working constancy that you like)
none of this formula is written in stone.
I apply several coats over several days wiping off the excess before it 
becomes sticky.if open pore wood I scrub in the 1st couple of coats with 400 
wet or dry sandpaper.
the finish is idiot proof if you screw up simply wash down with a fresh coat 
and dry off. 
If finish is damaged or worn a wipe down with afresh coat will do  wonders
If dirty wash down with the finish materials and 4o steel wool.
finish must be started on bare wood.
