Is it better to do this in a warm temp? I want to get the fenderwells done on a car I want to assemble over the winter and it's going to start cooling off here pretty quick. Sheldon

I use a little different method, I took a shutz gun and drilled the end out wider, Thin coats about 20 mins between and i use real low psi 15-20 lbs.. It spatters and spits out of the gun but its the closest to factory I've been able to duplicate..

Remember to mask the small holes in the aprons.

You need to be sure all of the right components are attached before spraying. In this pic you can see that the fuel tank, spare well and floor pan plugs, shocks, axle bumpstops, fuel lines, brake lines, and fuel vent hose cover on the drivers side, etc. were installed first, then undercoated. 7860521-BeforeSteamCleanWheelTubs.jpg (159 downloads)

Mine was only sprayed where you see it in the pic posted above, nothing up front. The way it's sprayed would give the impression that all they were trying to do was to coat the wheel wells, trunk extensions, and axle hump area above the axle, anything else was collateral coverage. Keep in mind that it was not called undercoating when used in this way, it was referred to as "Sound Deadener" which makes sense as this is where rocks would typically hit in normal driving. The "undercoating" option was an entirely separate process and included a hood pan and typically a much more thorough covering.

AH! Thanks for jogging my memory Scott, reminds me of a question I have been meaning to ask. My October build blue '70 GTX has what looks like factory "undercoating" on the floorpan that I was pretty sure had been there since day one but don't have a build tag or sheet. I just took the hood out of storage where it has been lurking the past 20+ years and noted it has a thin coating of the stuff on the underside of the hood too, the same factory looking black textured stuff. Thoughts? "I think its got a hemi"

Thoughts? The under coating on the underside of the hood is the clue. Full undercoat cars SHOULD have received a hood pad, so there wouldn't be undercoating there. My guess is that the UC was dealer added or by some aftermarket company back in the day, it was a VERY common "Day Two" add on, especially in the rust belt states.
