Been researching ways to preserve/protect patina. Penetrol and boiled linseed oil seem to be the most used methods, but I’d love for somebody to lay out the pros/cons of each and help me decide which method is best for my situation.

Got a ‘78 big ten. Buckskin and frost white factory 2-tone paint is in decent shape for its age...still some shine to it in many places...but it’s also got plenty of patina. Some areas are bare rust that is pitting and I’d love to stop it or slow it down.

I’m a driveway mechanic, no garage or covered carport to work in (though could borrow a friends garage for a weekend if need be). Truck is always parked outside, and I live in Austin where sun and heat beat down from April through October.

Curious to hear your thoughts!

A friend of mine used Owatrol Oil on his 63 GMC panel truck to preserve the patina.
I use it on the bed of my c20.
It can be applied with brush, roller or sprayer.
It holds up very well but my I don't drive my c20 in winter and it's parked in a garage.

There is a company called Sweet Patina that sells a mixture called patina sauce. I’ve seen very good reviews for it. A different route if you’re interested

Is it forgiving enough to be applied out in the open or would you only do it in a garage? And how does it look when applied over non-rusted surfaces?

You can apply it in the open it takes ~ 24 hours to cure at 68°. It would collect a dust and bugs, I would recommend to paint the truck indoors.
It has a kind of semi gloss appearance on paint and rust. It should be wiped off it from the paint when it's wet cause it doesn't hold up very well on paint and bare, rustfree metal.
The rusted areas look a little darker with the oil applied.
Best would be to test it on a small area of the truck.

Owatrol Oil looks exactly like the sweet patina stuff:

Been painting residential for 38 years. All the products mentioned most likely have linseed oil as their main component . It looks good on totally rusted objects and lasts 6 months or so depending on weather conditions but it looks like **** over painted areas. Another method is to buy catalyzed polyurethane clear , mix up a pint , cut it heavily with acetone and rag or sponge it over the rusted areas , dries very quick and holds out rust a long time. You can add flatting agent to adjust sheen level. I do this same thing on my cast iron table saw top. Lasts a long time outside.

I had a hunch that all these products shared a common base. Think I might try either boiled linseed or penetrol first in the bed and see which one looks better. If neither suffice then maybe I’ll try something more complex. Thanks!

Dont bother with penetrol. Buy Raw linseed oil instead. It’ll set up quicker.
