Best clear underbody protection

[Skyedriver]

TVR 350i (Wedge) newly refurbed chassis and suspension, all painted or powder coated white. I want to use the car but don't want to ruin the expensive and extensive renovation underneath. What is available to apply to protect. Or do I just wash it with a hose every time I go out....

Bilt Hamber do a great range of anti corrosion products, I’ve used them on my Porsche 911. The offer good protection without the muck of waxoil. Have a look at their website.

You could give this a go, not tried it myself.

Taking a leaf out of the Biker's book, I went for Corrosion block (Slightly thicker ACF50) to protect the underside - It's just a clear film coating, so it won't protect from rockchips etc., but it should do a good job of keeping the rust off.

I've used Bilt Hamber Dynax UC (clear), but not UB. UC is easy to apply and leaves a translucent yellowish film, so you can still see what is going on beneath. I don't think it has the staying power of UB - it doesn't really set, but it's probably a good choice for TVR outriggers, where you want to see what's going on beneath the wax. The Bilt Hamber cans are pretty good too - they come with a lance and the cans can be used upside down. Useful if you'll be re-applying yourself every few years.
