John, Steve, or anybody,

Please post a picture of how the original undercoating looks now in the wheelwell.
I'd appreciate it!

Phil,

I can't help you there.  My undercoating in all wheel wells was freshened up at restoration time.  I never touched the underside of the car though.

I'm sure John's car is a treasure trove for this kind of information though.

Mine isn't representative of factory production in that area, as it was dealer-undercoated and has full coverage in both front and rear wheel wells.

So, the factory coverage was partial? Where? (That's what I'm trying to figure.)

The coverage in the rear wheelhouse was pretty much front-to-rear, but in the fronts it was pretty much from about 12 o'clock rearward, with little or none in the front half.

Thanks a million, John!  The previous owner of my car did the black underbody painting, but it appears he did not do the wheel wells.  This helps a lot.

On the front inner wheelwells, did the factory spray the undercoating on the front wheelhouses before they were assembled to the front fenders, or after the complete front clip was installed on the body ?

The front inner fenders were sprayed with undercoat (actually sound-deadener) material after the front sheet metal was installed, at the end of the overhead chassis line, as the car went through a spray booth about six feet off the floor, just before the wheels were installed and the car was set down on wheels on the Final Line.

Great commentary guys! When I restored my LOS 69 and staem cleaned the engine bay only a very small amount of the dealer installed undercoating came off in the transmission tunnel area and was very easily freshed up. With 99k on it and originally from Garberville, CA area, the rust was MIA totally. The undercoating did a fabulous job and I would never think of removing it!

When doing a frame off restoration, you only want it in the rear wheel wells and a small amount in the front (I have seen several with very little in the front and this never looks good IMO).  Do not install it on the floor boards or trans tunnel.  If you do, you'll get docked at a national judged show.

Jerry will you be docked points if the undercoating is NOT put back into the wheel wells?  I have been considering the undercoat in the wells like the AIM shows.. but it just looks so darn clean down there!
