i mean there are boatbuilders in us as well that use similar or same products, are there no boat builders u can check with instead of importing chemicals into us as i dont know regulations about that i know sweden has some rules so u cant import some things without checking rules first and checking with chemical inspection wich is a part of the state if chemical is legal to import or not. and from experience they can chenge the name of it only to confuse the customer even more even thought it might be the same or very similar product, you got 3M and du pont which are very big chemical corporation, i bet u can find that product in us cant be a big place like that not having what youre looking for.
