Undercoating this weekend; What to spray?

[CoronaRaptor]

Yes i think it is 409 grade stainless which will get a coating of rust on it but it will take quite a few years to rust out but alot of the hardware- nuts, bolts, flanges and hangers are not stainless and will rust out or be very difficult to remove if it ever needs torn apart. Spraying it with boiled linseed oil will combat this. Alot of it will burn off up front where the exhaust gets hottest but at the back where exhaust rusts out the most it will stay on there for a while.

It never hurts to coat metal, I agree. I hate rust.

Has anyone here used it?

You can buy boiled linseed oil at home depot, about $25 for a gallon. It will take about 1-1/2 gallons to do it. I spray it with a parts solvent sprayer and compressed air.

Could you use one of those 2 gallon pump sprayers that Home Depot sells? Or is that stuff too thick?

Not sure, i have thought about trying it but never did. I do usually stick my container of linseed oil in a bucket of hot water to heat it before i spray it so it sprays easier. 1 thing that is very nice about boiled linseed oil is once it dries you don’t get all greasy and dirty when you touch it or work on your truck! Believe me it works great!

I actually bought stock ones for a 2002 ranger from rock auto and they fit pretty good.

I'm about to bring mine in to a local coating shop where they will be doing the entire underbody with Tectyl 2102 for about 475 USD.

View attachment 152648 View attachment 152649 this is what i did on my f150 to protect the turbos and exhaust manifolds from splash.

Great job. Might you have a part number?

Thanks

Use straight boiled linseed oil. I have a 2002 ford ranger i purchased new and to this day there is no rust under it. I live in northwestern PA so the winters are pretty brutal on vehicles up here.

How do you spray it, without making a mess ? Is it something one can do themselves?

I jack the truck up outside and put it on jack stands, you have to wash the truck after you are done to wash off any overspray. I do it myself every year. You just need an air compressor and a solvent sprayer, one of those cheap ones, harbor freight probably has them.
