RE: Balsa USA Super Cub Build
You got that right! My Dad used Dupont Imron on a full size Taylorcraft when it first came out and there weren't a lot of safety regs. on that type of paint back then. It restricted his blood vessels down to the point it gave him heart attack. He was spraying it and was only using a cheap dust mask. I have also had my bad experiences with urethane paint and improper ventilation This type of paint is Very Dangerous!!
