I am not sure what VHT paint, Colour you are talking about? Were do you want to paint and in what colour. OK, you want matt black fins. Use a VHT caliper paint for that but, must be baked on. If you need more info i will find some links but, USAutomotive in Bedford do a very good VHT caliper Matt paint. Silver, use SIMVHT31C also needs to be baked.
