I have used this stuff and it does a good job, goes around compound curves and handles cold OK. It does have one big problem though..........it should be used one day only! If you leave it on for 3 days, it turns into a gooey mess! We used it on our ASH-25 which took something like a half roll per pop. If you put your ship back in the box each night, it's the way to go. Save the $9 per roll stuff for the contest flying. Can't beat the price,
