Tooling Gelcoat suppliers in UK

Has anyone found a supplier in the UK for tooling gelcoat? The closest thing I can get other than normal gelcoat is:

“GC206 VINYLESTER GELCOAT
A vinylester resin-based gelcoat offering excellent weathering, heat resistance and mechanical properties. Ideally suited for mould making.”

Does anyone know if this will do the job?

Thanks in advance.
