It looks like I'll be pretty much stripping the whole of the underside of the GTV, so I thought it worthwhile to give it a coat of something. Obviously if this was an everyday car used in all seasons in the UK I'd need to go overboard to keep it in one piece. BUT the car is only really going to be used as a toy, and then probably only in good weather.

So what would people recommend using to keep the underside in top condition?

Cheers
