Good point that there's a better reason to use an additive.
Any idea roughly what fitting hardened seats would cost? Wondering if it's worth it now that I'm not doing as many miles in the Marcos, or if I just keep using Valvemaster
I charge £110.

I'm sure you can get more for your £110 as Phil would be cutting new seats anyway? New, tapered guides & multi-angle seats would make sense.
