Anyone familiar with oil-based undercoating?

My Safari van is one of two vehicles I own. I have been considering getting rid of the other vehicle and keeping the van as my full time, year round ride. The problem is I live in Michigan (rust belt). So my concern is protecting it through the winter. Is anyone familiar with oil-based rust proofing?

Sounds messy. Why not go with the tried and true Fluid Film? It's a waxy coating that wont attract dirt and you can apply it yourself.

they sell it by the cans but you want the type that dries fully or cures. ow if the van has any rust on it already you will want to clean under it super super good or it will still rust. And fix /neutralize the rust that is present prior to spraying. I grew up in Maine so I have dealt with the rust quite a bit.

I recommend you go to the snow plowing websits,and read up.These guys stay up on this stuff.But, fluid film has been a well used product,by them, even though it is not permanent.It does not trap nor hold moisture.

Agreed. When I lived in NY, I would apply FF every year in the fall, and it worked as intended.

I use Amsoil MPHD Heavy Duty Metal Protector.

Aerosol that goes on like oil, and hardens to a wax finish in 24 hours.

Spray all my inner panels... trunk, hood, doors. etc.

Never did it on the undercarriage, but it would work.

When I was a kid, there were shops that would put your ride on a lift, and spray it with old motor oil! Just a bit environmentally not kool.

This stuff really is the most effective product, but it's not cheap and damn does it stink when youre trying to spray the undercarriage. It's also difficult to use in the frame rails, because it doesn't have a 360* sprayer.

Getting undercarriage car washes when you go on salty drives is also very helpful. I do that and have a shop use a rust spray product every year.

I am a believer in Fluid Film it works great but a bit messy so I like to do any undercarriage maintenance before it gets a fresh coat. I've also been using No-Drip from Old Dominion it's the same consistency as Fluid Film and comes in yellow and black they sell a gun kit for it and it stays moist but doesn't run or drip off and it is body shop friendly
