rust prevention before winter

[rbeach75]

Dear All,
Im trying to apply anti rust paint to my truck this weekend for the winter and or longetvity of my truck. i was just wondering what products are best and what kind of preparation i need to do. also i'd like to keep this relatively cheap but for quality i will spend the money. thank you.

I haven't done it yet, but I'm gonna pick up a cheap paint sprayer and use old oil and spray that on.

I also would like to hear some responses. I just got my truck and the underbody is pretty rusty. Ive been told to spray everything with Eastwood Rust Encapsulator. Good idea or no? Any better suggestions?

Those "rust conversion" brush-on jells (the kind with no prep and turns black and glass like) don't last long and I don't think are the best choice.

Por-15, or KBS have good products. It's not all that easy to prep with (nothing good is going to be) but if you do it right, will last a long time. This is a scrape, degrease, phosphate etch, paint X2, topcover, process.

Another alternative I use for all my brake/fuel/trans steel lines is to coat them once a year with LPS #3 Corrosion Inhibitor (Home Depot now carries the PB version that looks good and is easier to find). It's a aerosol spray that has a waxy coating that does a really good job of protecting steel stuff. I've been blasting my oil pan for years and it looks New! I just HATE replacing steel brake lines and still have the original ones on my trailer that are 15yrs old and parked on dirt & grass year round.

You could do a yearly spraying on everything under your truck I'm sure and stop further corrosion I'm sure (might take 1/2dz cans though )

Thanks for the suggestion. I was leaning away from POR 15 and towards the eastwood stuff because of some good info from other forums. Biggest reason was because of the prep. They say just scrape off the loose stuff and it will work just fine. It would be awesome to scrape, degrease, etch, paint.......... Just alot of work Ill have to figure something out

POR-15!! I've used it on a lot of trucks stuff is awesome! Little bit of prep work but way worth it.

Kbs is just as good as por-15 just a little bit cheaper. I have it on my truck and it works good but it is still hard to get in the areas that need it most (like in the rockers, cab corners, and rear wheel arches). This is where I spray the waste oil on. It works best to get a under coating gun to do this. A paint sprayer doesn't work unless you really dillute the oil and then it washes off to quick like wd-40.

I have used POR15 many times. Many restorations. I have used it on fresh metal and it was perfect. I have used it over existing rust - horrible results, helped make the rust come quicker.

You didn't do it right then

It's all about a proper prep. If you're going to stop the corrosion and prevent it from happening again you need to put the effort in......

I wish that was the case! Don’t get me wrong, we still use it on some cars in some areas. Now if we are doing an 80k resto, believe me this stuff wouldn’t even need to be near one of the cars (why rust proof something that doesnt even get breathed on!)

But someone told me the stuff doesn’t hold up. This was crazy to me because I loved using the stuff. At the time I was driving a beater Fairlane. We painted potion of the frame with a rattle can and a portion with POR15. And I really wish I was joking but the POR15 didn’t hold up any better than the painted area.

Again, not knocking it completely, might have been a fluke! It was prepped correctly (unfortunately I know how to do a perfect prep job).

I now use it on the inner floors of cars I do.
