Not a lot but don't want to worry about not being able to wear them in the rain due to spotting or welting.
Thanks for the responses guys. I'll pick up a bottle when I stop by Alden DC tomorrow. Last week I got lucky in that I'm pretty sure I parked illegally in front of the store due to the construction signs and didn't get a ticket. I planned on being there for 30 minutes and ended up being more like 90. Hopefully tomorrow is quicker than that and I can get off easy again. Trying to find parking there is pretty rough.
