Hi guys,

I was telling a mate about the weak 4wd cosworth gearboxes and he told me about Fin 25 Teflon additive that I should consider. He used it to overcome gearbox reliability problems when he maintained emergency response vehicles at the airport.

I'm thinking of using Fin 25 on my standard gearbox, and was wondering if anyone has any experience using it?

Here's their website: http://www.interflon.com/gb/products...e-nt500-fin-25

Thanks,

Rich
