When we were approaching the painting stage of our Searunner34 project
... (about '94 or'95), I sent for a test kit, and let a sample "painted piece of glassed ply" sit face up in a pasture for 6 mos. It started chalking, so we opted for the tried & true solvent based LP paints. This could have been an unfair test for System 3 however, because it was new, and the "kit" did not include the catalyst! They said that for testing purposes, it was not necessary... Go figure?
System 3 comes out flat to smigloss, which I actually prefer to the incredible shine of Sterling, or Awlgrip. In fact, on my previous boat project
, I added flattening paste to my Awl Grip to lessen the shine. The thing is, this shortens the lifespan of the paint
, so we went with full gloss this last time. (first Sterling & then Awl Grip)
The System 3 may or may not have a UV problem? As I said, my UV test was moot. I can however offer these observations: (we did get a Qt kit with catylist, to do some areas)
If you want it glossy, clearcoat it. We did not.
I had no sucess trying to roller tip the stuff and getting decent results. (just like the other LP paints) It is a skill I just don't have. So I always spray, except touch-ups or inconspicuous areas...
As previously mentioned, Systenm 3 LP is in fact hard as a rock! (WAY harder than the others) Also... for painting in areas like wet anchor
lockers, or in our case the cockpit
subfloor, it holds up long
term to constant moisture, even trapped against it under a fuel
can! This is not true of Sterling or Awl Grip, which would definetly "bubble up" under these conditions. So, I would definetly recomend it, at least for such areas... About the whole boat, more testimonials are a smart move. We expect 10 years out of our Awlgrip, with the last 5 being mostly flat & getting dirty easily. (Attached is first Sterling job)
Good luck, Mark
