Rust question...

Hi guys,

For the 2nd winter, I'm driving my lude ( I'm from Montreal). Last spring, I had to repaint my rear panels because of the rust. I wasn't sure yet if I would drive it this winter but in the end I had to. I did a rustproof right before winter started. A few days ago, I noticed rust coming out of my rear panel, already which I haven't noticed last week. Cold/warm weather' effect? Poorly repaint or the rustproof was ****ty. I'm so mad, I'll have to repaint it again.

Thanks

Re: Rust question...

From what I understand, if you simply painted over the rust to hide it, the rust will eventually come back, and severely at that when exposed to salt/snow. To eliminate the rust problem, you need to cut out the quarter panels that are rust-infected and weld into a new piece of metal, THEN do the rust-proofing so that the new metal isn't as easily exposed to road salt. I used touch-up paint just to mask the bubbling temporarily until I save up for quarter panel repairs. I live in Toronto and my rust is pretty bad...

For those who have fixed quarter-panel rust, any input on whether they started to rust back after a year or two?

Re: Rust question...

The panel has been sandblasted but I did the rustproof like 2months later. I'll try to post some pics. later you can see it when you're close only. It sucks still. I may have to store it next winter

Good point on taking care of the rust properly. The best rust prevention is washing the car regularly. The salt and water mixture is harmful only when it's above freezing temps (32 degrees), if it's lower then 32 you don't NEED to wash it, but I still usually do. At least 2 times a week I'm washing it.

My friend never washed his car in the winter, ever. There was absolutely NO rust on the outside of the car. But when he parked it in his attached garage (attached garages are warmer because of the heat from the house), all the snow/salt would melt. It rusted the engine bay and under carriage pretty bad. He needed new fuel and brake lines, and all the bolts were rounding because of the rust.

From experience with other cars, the rust usually finds its way back. After you have the panels fixed (if you do it yourself) make sure to use a high quality, rust preventative base paint like Rustoleum (can be found at walmart). I even use rustoleum on the rock chips on the hood. Just like panel rust, you have to make sure you're at bare metal before you can paint it, I use a screwdriver, or something similar, and pick at the area until I see bare metal then paint and it looks fine.

Re: Rust question...

Rust is like cancer.
The only way to PROPERLY deal with it is to cut out the affected area, in addition to a bit more material, and reweld new metal in.
Sandblasting alone only gets the rust on the surface; there's still rust thru most of the metal, most of the time.

Re: Rust question...

what about rust treatment spray? the stuff is supposed to bond with the rust and become some inert black stuff but i've never used it. I have a door thats rusting on the inside from a bad window seal and i'm going to try the treatment stuff because of its awkward location. i'm wondering if i'm just putting a band-aid on it or if its going to last

Re: Rust question...

If it isnt a heavy rust it is best to use sealer primer after sandblasting. If it is bubbling under the paint you may have to cut out the section and weld in some patches.

I had to do this on a prject minitruck I built a few years ago. It was alot ofwork but worth it in the end.

I never knew that salt is exceedingly worse above freezing temps. I was under the impression that salt would corrode the metal regardless of temperature, especially if rust already exists on the metal. Now I'm worried cus Toronto has had some pretty mild weather lol. Cold enough to snow/rain overnight for the salt army to respond, but warm enough during the day. Guess I'll be washing the car this week lol

I plan to bring the car into the shop for a ~$1500 (not including trunk hole) rust job this summer. I'd do it myself, but I have no prior experience in cutting, welding, painting (well, anything really), nor anyone to help me out. I just hope the rust doesn't come back after a year or something.

Winters..

Re: Rust question...

Hey if you're in the montreal area let me know, maybe we can get a group deal ;)

Got my whole car repainted last summer (only place I had rust was the REAR quarter panels and they were FINE when they came out of painting (I Had asked the dude to cut and weld new metal, the dick just bondo'd it all) anyways, I had my rust back about 4 months later, I even put my car away for the winter. Lesson learned? Don't go budget, or stick around when he repairs your car to see he's doing it right.

I'm stuck repairing it again too now...

Yeah we've had an extremely mild winter compared to the last few. Last year I spent about $20 at the self serve wash, this year it's closer to $40 already because its been so warm.
