I’m very new to shaping and glassing - my wife rode the 8’4" I built for her this past week and had a blast. I have a few boards planned for coming weeks/months. Up here in the PNW the days are getting shorter, colder and wetter - but we still get some sun on those colder days.
I’m considering using UV cure polyester resin for two reasons - longer open time while I’m improving my glassing skills, as well as potentially allowing a quicker kick in the sun on cooler days. Is the lower temp and humidity going to cause me the same problems I’d have with MEKP?
Am I thinking about the use of UV cure resin wrong? Anything I should consider for glassing later in the fall/early winter?
I’m in the NorthEast. As long as its sunny and in the 40s my shed will be about 60 inside with the lights on. Bring your resin indoors the night before so it not freezing cold. Cold resin doesn’t flow out or wet out as well. As for curing, as long as you can get direct sun on it it will cure real quick. A trick I use in winter is my shed is painted light grey and reflects sunlight very well. When the winter sun is at a low angle I go to the side of the shed facing the sun and take full advantage of the reflection. Cures just as fast as summer when the reflection is working.
As for humidity, that is a question I can’t answer as I plan my glassing for full sunny days in the winter which usually means dry post cold front weather.
You can always use regular cat with sun-cure as well.
Better to have a UV light source indoors. Always use a small amount of catalyst just in case it rains for forty days and nites, like it has lately. Better for someone just starting out to use the pre-mixed. I’m in Pacific City. Believe me I know. Lowel
