Light Rust- Tips for Treating

[Izanewman]

Hi folks,

I'm hoping someone can help with my question. I have a 99' SR5 that I purchased a few weeks ago. The vehicle is in great shape with the exception of some light rust under the vehicle, on the hitch, and some of the fender parts.

The vehicle was driven in PA. for most of it's life. Road salt is the obvious culprit. I inspected the vehicle carefully and did not find anything with severe rust problems, but I would still like to treat it.

I plan to go over all parts with a wire brush and then repaint. Would it be wise to use a product to first stop the rust prior to painting? Will a product like Rustoleum be a good choice? They make general purpose black paint and also a product to "kill" the rust.

Thanks for your help folks!!

POR-15 is popular with many...

I use naval jelly myself. It's cheap and easy. Just make sure the parts are cleaned well before painting once the naval jelly dissolves the rust.

I've actually used Permatex brand Rust Converter. It works, and it's made for light surface rust.

Guys, thanks for the suggestions so far!

I've been reluctant to just spray over the existing rust for fear that it would keep doing it's thing under the fresh paint. Someone already tried that on my hitch and I flaked off a piece of rust that had bubbled up just the other day.

Seems like most everyone is saying to treat it prior to painting. Some good product ideas here as well.

Thanks!

I live in Pennsylvania also and have rust in the same places that you have.
A couple of years ago I used POR-15 on the problem areas. It has held up VERY WELL since I applied it. Unfortunately, back then I only applied it to the rusted areas. Since then, other areas rusted so back around Halloween this year I bit the bullet and did as much of the frame and undercarriage as I could get to (using a lift).

The key to using POR-15 successfully is to follow the manufacturer's directions EXACTLY and use their other products as indicated. 99% of the time when someone complains that POR-15 did not work it is the result of them "knowing better" or "not wanting to spend the money on the other prep products".
Yes, POR-15 and it's other prep products are not cheap but they DO WORK when used correctly.

For more information about this product check out their web site at: POR15, Inc. - Stop Rust Permanently - Repair Gas & Fuel Tanks

FYI, if you use the following code you get 10% off of your order as long as you place an order before January 1st. Code = PCAA1209

I usually order the 6 packs of POR-15 since a little goes a long way.
The 6 packs are more expensive but they keep better/longer than the quart cans. With the 6 packs you can also order a combination of different colors if you need them. For undercarriage I stick with gloss or semi-gloss black.

BTW, I have no connection to this company other than being a very satisfied customer who has used their products on my vehicles for the last 10+ years.

Thanks Charlie!!

I have been reading up on this product and it looks like a good option. The only problem I am having is that I don't have access to a lift or even a decent garage for that matter. I have been calling around to local body shops and garages asking if anyone would apply the treatment. Nobody seems to want to deal with it.

On a side note, has anyone used or heard of the Rustdoctor products? They make a product that converts rust. They also sell a degreaser and cleaner that should be applied first.

Lastly, my main concern regarding the rust is the effect on brake components, particularly the lines and hoses. I don't see a good way to treat this other than to keep the connections sprayed with WD 40.
