Hello All,

I live in S. Florida and see no snow or roadsalt, so i was surprised to see such bad rust on my Radi support. It was so bad I am giving fair warning to inspect it, with this post. ITS LikE IT WaS A 70's vw bug chassis.

Bad news begins.....When I removed my front bumper last weekend to put on the lower VR6 bump spoiler, the Radi support has rusted very badly. Not as bad as the pic on Dans DIY page, (These are Dans PICs) but rusted none the less. Its very common prob. I was working in the wee am hours of the morn, so I snapped no pix. I took a very coarse wire brush and got too work.

I brushed off all the rust i could see, vacummed and blew it out with a shop-vac, cleaned it off with degreasing soap, water, & a 2nd straight de-greaser, then rinsed with water. Allow it to dry thoroughly.
To slow the rusts pace I hit it with several coats of a *Hi-Heat ultra flat black Rustoleum* spray paint. The stuff used to paint bbq grilles with. That should slow it down a bit but you may want to inspect your mk3 now. If you get snow, lots of rain where u live, then its started.

MR Reed Has a gr8 fix from the vortex on this issue as well.

An early warning may help.

I found some even worse rust on the rear passenger door. In between the 2 hinges , dead center, the arm housing where the rubber circular gasket attachs to the door. The whole circle is rusted out. Man I am bummed. I just cleaned up the radi support. This will require removing the entire door.

I feel pretty lucky. The only rust I've got is down where I had those ants living a while back, and even then, there's very little there at all. Of course the whole bottom-side of the car is covered in surface rust from its first 9 years of life being up in the northeast.

My springs in both front and rear were actually "fuzzy" from the rust. Flakes were coming off and everything. When I replaced shocks and struts, I took a wirebrush and got rid of everything that could come off, and then it got four coats of grill paint. Seems to work fine. That was several months ago and I don't see any signs of chipping/cracking/flaking, so I guess the paint holds up.

I bought an 18oz spraycan of Bondo Paintable Rubberized Undercoating an it is awesome for such dilemas. You basically spray on a protective rubber coating that will cease moisture damage.
I'm even going to use it as a one shot deal to reseal the inside of my cowl tray, that houses the wiper assembly and ecu. And since i have a white car, that cowl interior area is alway dirty and dis-colored. So i will leave it the blk rubber color.

BTW it also deadens sound from the notoriously noisy MK3 engine bay & road noise.

I was just under there changing my oil today and took a good look at it, and right around where the motor mount is, around the edges there's a little bit of rust, but the radiator support itself looks brand new. I'm actually quite impressed. Either somebody had it replaced, or I've got the "one in a million" case of mine being undamaged after spending 9 years in New Jersey.

I also really need to pull mine and have it powdered or repaint it with a rust sealer. The part is cheap enough used, but shipping it might get costly.
