I live in a town that got its start working the water. So as far as rain gloves, I've thought about buying/using the same gloves the watermen do. If I get a chance today AND I remember. I will take a picture of the gloves.
Other rain gear...
I purchased a new rain suit. Kept me dry, but got a hole burnt in it because of my exhaust. (Company replaced it, free of charge.) I have since decided to an archery arm band around my calf to keep the excess from touching the pant leg. It works.
Boots ... bought leather motorcycle boot that say they are resistant. I applied 'sno seal.' & it seems to have helped.
