...man, regarding cartridges, 6 months!? may be you glass a few boards...
They last around 9 hours of full use.
Howzit reverb,I used mine for around 10 hrs, then when I cutback on boards it was 1 set a month and in a ziplok bag when not on my face. Aloha,Kokua
First post.... I think the questionmark here (not answered as far as I've seen?) is "isocynates."
Apparently, isocynates are too fine for most masks, including those pink ones made for paint & chemical fumes, to filter out.
Does anybody have info on whether/which surfboard epoxy resins do or don't have isocynates, and whether there's a mask that filters them out?
The only comment I have to add is that, in all seriousness, I seem to be dumber and to have crappier balance since I started shaping.
But I'm also getting older so.... Fuggit.
FWIW, this autopainting thread recommends you change the cartridge every day when working with isocynates (why is explained in thread): http://www.hotrodders.com/forum/epoxy-primer-fumes-50552-2.html
