The glue is HH-66There is special tarp glue that is used that works well. The tarp has to be clean before you glue it. I will sometimes use paint thinner to clean it. You brush the glue on both surfaces and let it dry before you put them together. This is what the professionals use and it lasts for a long time. It is easy and cheap to do. You just need to get the right glue and some pieces of scrap tarp material to patch with. I wish I knew the number of the glue. I know our New Holland dealer sells it and it is sold by many different suppliers. It is a white can with green letters on it if I remember right.
