wood oil with uv filters in

[gary3029]

This past season tried a little experiement, which started by accident. My hatch is on runners which every few weeks over the season I would put danish oil on...worked a treat. There was some varnish work near to this that got splashed and I brushed it off. Next time went down noticed that water was not sitting on the varnish but was running off like polish. So every few weeks as normal running upkeep I put some danish oil on the varnish that side but not the other side.
Have just got the boat out and where I have been putting the danish oil on the varnish there is a better shine, water does not sit on the surface and the varnish is in better condition then the side which had had no oil, no peeling. I know the oil is for the wood, but it does not appear to have weakened the varnish, it has kept rain waterfrom sitting on the surface and looks better than the other side, which were both revarnished at the same time and have same wear and tear.
I am going to repeat this on another part of the boat, but I was wondering if there are any oils that have UV filters in which would help protect the varnish surface even more from breakdown? Would there be any long term problems to this practice?

That's very interesting; I'll look forward to reading of your extended test later on. I don't know of any oils which have UV filters in them naturally, but Sikkens make an oil which they call Filter 7, which I found to be quite durable when applied over their HLS oil.

They say the best cures are discovered by accident, seems like you've stumbled on one. All varnishes I know of say they last up to 5 years, but I've yet to find one that isn't affected by UV (not that we get much here) after a couple of years. Like Peterduck it will be interesting to hear about your later tests. I can already think of several uses for this and not just on the boat. Keep us posted and don't stop experimenting.......well done.
