1991 Defender 90 Military
Considering having a local shop apply NHOil Undercoating product to my '91 D90 Mil. Has anyone else had experience with this product and is it something I need to do every winter?
I rinse the chassis with a regular garden hose. It seems to stay on. I don't pressure wash it or do to a drive thru car wash which uses high pressure chassis sprayers. I do have to say it's been holding on pretty good. I only drive it in the Spring, Summer and Fall. No Salty roads for the classic cars.thats impressive. fluid film requires annual application.
