Yearly oil coating is way more important to keep cars less rusty underneath. Also special attention to rear fenders and grommet holes or exposed bolts.
Source: I restore and maintain cars in New England, near the nice salty ocean air to top it all off.
A youtuber, mustie1, uses bar and chain oil in a sprayer and has shown that the coating lasts for years.
Yeah, any sticky enough oil will work, people used to use old motor oil back when 20-10W40 was the norm.
They make some waxier oils now and it’s more popular in Canada.
Oddly enough I live not too far from that Mustie guy. Haven’t watched too many of his videos though.
I got onna those giant cans of pb blaster for my 01. Glad I did.
If it’s not already rotting away too badly there’s still time to coat it this fall.
https://nhoilundercoating.com/ Is pretty good and comes in big buckets.
It's all surface rust for the most part. The worst of it was a flange gasket on the exhaust but I replaced it.
Any point in using it with a 10+ year old car with rust?
Sure, it won’t fix the rust but it’s ll still slow it down and keep more from happening. I’m doing my new-to-me 2016 Subaru this fall. It’s not terrible, but seams and edges are already crusty.
