Hi All,
When building a 12" coil here outside of Houston, TX (elevation 43',
100% humidity/temperature) that was shipped to Kalispell, MT
(elevation 2954', low humidity/temperature) I too used Marine Spar
Varnish and have had no problems with the coil.
God Bless,

Hi Chris, Robert,
Interesting! I'm in CA these days but started coiling in Minnesota
which is cold cold cold. I didn't use PVC but sonotube at that point
which I did coat inside and out with a thinned-out urethane (to
absorb into the sonotube). Due to the temp swings, I decided to use
Marine Spar Varnish for the outer coating. This particular varnish
remains flexible (hard to the touch). I've never had any problems
with cracking, shrinking, expanding, etc.. Just wanted to mention
that as it's available at all hardware stores. Even though I'm in
sunny CA, I still use the same varnish. It's been a nice varnish and
goes on thick.
Take care,
Bart
