For a hull In my personel experience as a laminator i would never have a boat made with a chopper gun having worked once where it was tried,we soon went back to hand lay up, and i would never do it again and this is also the general opinion of any decent laminator i have worked with over the years.Sure it may be quick, on a flat surface but try spraying somewhere more tricky and getting the correct thickness of glass down, no one can spray as accurate in weight as to when it comes of a roll ie,one part of a square meter might vary considerably to another and any parts you cant get the gun to spray you have to hand lay anyway.Also as someone has said you can't spray a cloth or woven roving etc.The resin ratio can be set but the operator can spray more resin alone if required.what about the matter of health and safety?I could go on.The only good thing is the percentage of waste goes down. ![]()
