Jay,

I have used both Captains and Flagship extensively. Put one kayak with Captains next to another with Flagship and you will see a very big difference. In my experience, if you are applying by hand, Flagship is almost impossible to make look as nice as Captains. It looks duller and shows brush marks. The finish on my wife's Silver with Captains almost looks sprayed on. So, if you want the supposedly better UV protection, use Flagship for the base layers and top coat with Captains.

It may be technically correct that Flagship has 6 times more of something, but don't think for a minute that the finish on your boat will last 6 times longer. You are going to scratch it and wear it thin in places if you use it. It will need a new coat of varnish now and then much sooner than an unused boat.

: I just went into BoatsUS to get some Z-Spar Captains Varnish and they were
: out of it and said they would not re-stock it. Said I should get Z-Spar
: Flagship varnish. Flagship is $5 more a Quart ($30) but the label says it
: has 6 times the UV protection that Captain's had! Sounds like a lot less
: 'varnish stress' to me..
