This fiberglass laminate material from Tonchean is exceptional in terms of quality and durability. It has proven to be highly compatible with general polyester, making it ideal for industrial and scientific applications. The laminate's fine fiberglass gives an excellent finish that speaks volumes of its strength and reliability. However, the only downside I notice is that it can be a bit challenging to handle for novice DIYers. Overall, it's a great product and worth every dime.
