fwiw,
We use Penetrol as an additive for spar varnish, and it certainly helps me get a good fllow-out, especially in hot wx. Yep, I know that the pro's advise only varnishing under a rather narrow spread of temps and humidities, but reality often trumps advice!
But, I've never h eard of Ottawa Oil!
Cheers,
