Yes, my car actually had the original undercoating in the rear wheel wells. Very thick, with heavy texture, drips, and 'striping' where passes overlapped. Only some of the u-coat was stripped in the rear when the quarter work was done. So, the plan was to keep the original stuff and build up new u-coat in the stripped areas, then blend with the original. However, after Mike sprayed & blended the new u-coat, things went bad quickly. The new u-coat started to lift the existing stuff around the edges. When Mike started scraping with a plastic scraper, the original u-coat came off in big sheets. You could see the original Ash Gold paint underneath! So, everything got stripped, epoxy primed, then undercoated.
I'm actually glad it went down this way. I feel a lot better knowing that there is nothing hiding in the rear wheel wells.
For the front, I still have the original inner fenders off the car. They have heavy u-coat, mainly in the area behind the tire - just like the AIM shows. I tried all sorts of things to duplicate it, but I eventually just ended up spraying the entire inside of the new inner fenders with many coats of 3M 08883 undercoating.
