Periodic Undercoating
Posted: Wed Sep 03, 2025 7:59 am
I'm finally running out of the last of my 1st 5 gallon pail of Fluid Film after 27 months of coating most of my cars/trucks undercarriages every oil change.
My original plan was to switch to woolwax after each vehicle got an initial two or three sprayings of fluid film. I have changed out one of those vehicles now, so I'm wondering if I should just get fluid film or something else.
None of them look cosmetically bad underneath, so I think I'm going to do "clear"/yellow and not the black option for whatever I buy.
Options considered:
1.) Fluid Film - $168

2.) Woolwax - $239
https://www.amazon.com/woolwax-Lanolin- ... 104&sr=1-4
3.) B'laster - $213
https://www.amazon.com/gp/product/B09HG ... WVN9&psc=1
4.) NHOU (New Hampshire Oil Undercoating - $260 - Apparently a mix of petroleum oil and lanolin. They advertise that it includes mouse-out.
