Thank you for your reply. I have one request. It's not your product, but it's becoming an issue because the gel coat product is discolored among the interior facilities of the Cairo Project.So, I am concerned that there may be a problem with your product, so I am going to check the test data and spec for Gelcoat.If you have related material, please give it to me.This is for comparative verification, and again, it does not mean that there is a problem with your product.
