I just ordered 5 rolls from Auto Barn, 4.99 per roll. Same price at O'Rilley but shipping was much more. I sand and polish the outside of the lense before I take them apart. Easier to polish when I put it the vise, just need a touch up when put back together.
Definitely want to see how yours come out! I think if I could do them again, I could make them look much better. I didn't get smooth sets in the back and I sort of figured out how to do it by the time I was on the second lens.
