Aar1064 OP enthusiast A Joined: May 2013 Posts: 282 Ashland City, Tennessee	Ever since I started the restoration of my AAR I never doubted my decision to restore as close to factory as possible including the undercoating but here lately I've been thinking paint instead. The undercoating is on the build sheet and thus far I have stuck to the sheet with everything else. I have the time and don't mind the extra work to paint if in the end it's better for the car as far as a top notch resto goes. I don't mind the undercoating look at all (yeah I'm one of those that like it) but just want to make sure I'm doing the right thing. Man I love this car! All opinions welcome

It sounds like you are a bit like me, so I would do what the factory did (w/non undercoated cars) and undercoat the rear wheel wells as well as the front inner fender wells and call it a day!

If you paint it do it like the factory did, not totally painted body color like the top side. Man I love this car! All opinions welcome If you paint it, do it like the factory did, not totally painted body color like the top side. I am working on a 71 B-body and it is a factory undercoated car. We did it with dip primer and overspray like the factory. Took pics and then undercoated the undercarriage like it was according to the original pics we took. I like the results. Just be sure and use the correct undercoating and you will never have any problems cleaning it after it dries. If it were my car and I was doing it as close to original as possible no doubt it would be undercoated, especially since it was a FACTORY undercoated car and not done by the dealer. 69 Road Runner vert 69 GTX hard top 70 Road Runner 4 speed 70 Hemi Cuda vert

Think I'm staying the course and undercoating. 85% of it is there and pics will be taken as to what was undercoated and what wasn't. I've got the right undercoating already and even have purchased the gun. Now if we can have a undercoating removal party with free beer, hamburgers and hot dogs. Any volunteers? Address will be provided upon request

You could cover everything with undercoat after if you don't like it!

Although I do agree, it can look like your hiding something, but if done right, I don't think it does. 68 Road Runner, 69 Belvedere, 71 Challenger Vert 340 barracuda, 01 Ram CTD, 95 Ram, 04 Ram, 85 Daytona turbo Z 66 GTO, 06 Magnum RT AWD. 07 Ram CTD, 07 Ram

This There's always another option as well. Follow the above procedure and stop before adding the final undercoating, or just do the wheel wells like all cars got. You can always add the undercoating later on if you so desire. Don't forget, undercoating cars also got under hood pads. If you decide to leave off the undercoating, also leave off the under hood pad, again, it can always be added later but the clips will usually scratch your paint going in so be sure before adding one.

I started just with heating and scraping but realized it would take quite a while to remove it all. I searched around on Moparts to find a better way and glad I did because it worked great. It took longer than 4 or 5 hours like others have experienced but nonetheless 3000 psi and 220 degrees was a lot faster than scraping. I found that fender wells were the hardest to remove as well as the places that had it caked on maybe 3/8 inch thick. There wasn't a place on the underside where undercoating was not still on meaning what was sprayed from factory was still intact and hard. The places near motor and trans was easier to get off and I contribute that to the oil through the years. The wheel houses were dry and believe this was why they were so difficult. I used some aircraft stripper and it helped a lot. Still haven't made up my mind whether to undercoat, or go factory gray. Man this tough. Opinions still welcome. Maybe I should have a vote. 8243424-image.jpg (214 downloads)
