I am going to use a 36'' wing, but I have cut the fuse to 32 so I will go with that. Coro in my area is expensive! for two sheets of 4 mil 24x36 it is 13 bucks, it is 7 bucks off of the internet with shipping. What is the deal? One sign shop said they would give me a 4'x8' sheet for 18 dollars. Why are those small amounts so expensive? At harbor they are 1.22. that is too much of a price jump to be reasonable. Are they just charging a lot because they are not doing anything with it or what?
