The Underside

What is everyone using as protection for the underside of their cars, Dinitrol, Wax oil, etc?

normal Underseal for me.. Wax oil cavity wax as well!

don't think I've made the best choices but they'll do the job good enough for me  

Hotwater power washed floor pan
Removed sealer with grinder with wire brush attachment
Painted with two coats of epoxy mastic
Body colour coat
2 coats of laquer.

This will only be a dry day car.. but I didn't want problems later on so the extra effort should pay off

Well im jealous, mine's all weather all the time though.

Probably better then just working off any loose shutz and give the area a buff and zinc prime then just reapply shutz to the areas needed…

Out of interest my car before I attacked the floor pan was always done with waste oil - whilst really messy when first applied it sticks good and saved the floor of my car…
