i seen the a-10 in the above pic at monster planes, i was very impressed with the liquid sheeting. he had a partial plane there that you could see the thickness and strength of the liquid sheeting. looks like a wonderful product. i have yet to use it but that a-10 is on my wish list. but i cant say how far it goes or how much it fills. i have a feeling alot of that depends on your ability to sand before applying the product
