Anyone thought of Dinitrol? Comes in different constituencies for different places under the car.
I switched from Waxoyl to Bilt-Hamber Dynax S50 many years ago, following a review in Practical Classics that placed it top of all the underbody waxes in salt spray tests. I reckon it's brilliant, comes in amber or clear formulations is spray cans or tins.
I'm sure Dinitrol is pretty good, but I've been totally satisfied with Dynax so never bothered to change again.
