I think he thinks im going to steal his work or something idk. I am finally running out and wanting to buy some. He gets his in large quantities so I got it in a new container that had zero info on it. This now makes me realize that I dont know that much about gel coat. What is the difference between them. There is tooling gel coat and then epoxy gel coat? Is gel coat necessary for molds or can you just use resin as a first layer. I know this is pretty broad. I see in some posts that like some resins you need a wax additive for it to truly dry. Thanks. Sorry I am jet lagged from getting back to MN from Germany and I may be reading posts and mentally mixing my information from resins and gel coats and non of this may make sense

Thus it is harder wearing/stronger than ordinary polyester gel coat, it is normally a vynelester gel. I would also advise using R.T.S ( rapid tooling system ) to build your moulds. This is a much faster way to achieve mould thickness than using traditional methods . As you can lay more layers in one go around 5 to 6 at a time, rather than the traditional one or two. You do not need to use epoxy gel coats for moulds. Epoxy gels are designed for epoxy resins as epoxy will not adhere to polyester gel coat. Hope this helps? Kind regards The Fibreglass King

This product may not be available to you but it will give you an insight into R.T.S . They sell thus in the UK. But you should be able to get the same kind of system. There are also videos of this on you tube! Hope this helps. Kind Regards The Fibreglass King.
