I've seen those round balls of salt, I'll take those over the spray treatment they do now. Have you seen this stuff? Usually it's on the highways but I've seen them do side roads too. A truck is just spraying this brime right into the pavement...they say it's worse than the rock salt because the rock salt takes a little time to coat and get up into your frame, whereas the brine spray is instant and easily gets into all of the crevices and is instantly activated as a rust causing agent. Nasty stuff.

That brine also is very tough to get off the windsheild when it is kicked up by vehicles in front. Wiper fluid doesn't seem to completely clean it, usually causes it to streak.

Tell me about it, I've gone through 3 gallons of windshield washer fluid in the past month. I can't wait to get out of this winter, we didn't get a lot of snow where I am this year, but it seems like there's been some sort of little even almost every day...an inch here, some rain, a deep freeze, ice, a couple inches there, more ice. Salt salt salt salt. Brime brime brime brime.

Did an oil change the other day, checked the fluid film treatment I did back in November. I'd say it did pretty well so far...had to touch up two areas. But I don't know how much longer it'll last going through this winter. I'll do another application in May...then another in November. I've read that the more you do it over the years, the more it mixes with the dust and sand and creates a decent barrier. It's not the thickest stuff to begin with.

I've seen better as well but given the area this vehicle is in, it's fantastic versus not using anything and what that would have produced. I'd buy the vehicle in this condition.

Looks fantastic esp considering location and the fact that those cars are very prone to rusting.

I drive an ’03 Silverado 1500HD extended cab PU. It was used to launch and trailer a boat for many years. I also live in NJ where we have a brine-happy governor. He was unprepared for one of our first storms this winter so he has the roads brined even its supposed to be 40F and rainy, just in case!

The truck doesn’t have a significant rust problem but it has developed large areas of surface rust, no rust through. I’m sure this is from the brining. What has been the experience with rust converters followed by painting? Do the converters really work and what are the best ones. I plan to do this in the spring if it’s worth it.

GM trucks are factory coated with black wax. Petroleum products degrade and erode the wax. So any kind of petroleum-based oil spray is not recommended on GM waxed frames. Of course if all the wax is gone it doesn't really matter anymore. This is what I use on my truck it still has most of its factory wax. Rust converter on the left. Original frame wax aerosol on the right. And in the middle a wax that goes on everything else. Like brake lines. Bolts. Any kind of metal. Another thing I like about this method is things stay clean underneath. You don't get covered in greasy sand and soot every time you work underneath.
