Honestly I have little to write to help you. But your plan is what I have planned on doing exactly. Patch and coat. Mine are pretty ugly. I may try to make some new ones myself out of fiberglass. But I'm guessing I'll take the easy route.

I think that JimK has fiberglass wheel well liners available if you need to replace yours. Otherwise, you can use some sort of plastic sheeting that can be pop riveted to the original liner.
I think the addition of a truck bed liner spray would nicely cover the repaired area.

your wheel well liner, looks exactly like my 73/23
the wheel also broke the drain pipe above the wheel well liner.
I removed the HW heater, through the bath module, and repaired the plumbing
and liner from the inside.
here are some tips to read about the 73 models
http://gmcmotorhome.info/skin.html#REAR
on the 73 models, the down range of the air bags has to be mechanically
limited (- 2 inches) to keep the wheel from damaging the liner. The "up"
range of the bag was about +3", at 100#, which is ok. This is what I did
(more range at higher pressure)
http://goo.gl/h24Cq
I have put plastic wood on the "inside - top" of the liner, screwed the
broken parts to the "plastic wood" , used a urethane calk on the cracks,
and an aluminum plate in the wheel liner with calking and screwed it in
place. (time will tell).
I could not remove the cracked liner, so this was the method for now.

My right side wheel well was a mess. Broken in a dozen places with holes all over. I used a plastic soldering tool kit from Habor Freight and thickest plastic I could find (storage container form WallMart)for patches and welded them in. I tested the welds by throughing the wheel well at brick wall a couple of times and kicking them. The seams held. Get the seam areas as clean as possible, I use 80 grit sand paper. Always trim off any thin edges, like where a tire has rubbed through. The trick to welding them is to tack the patch panel in by just melting them together in a few places then melt a deep V between the panels with your Iron. Fuse them together by pushing the plastic filler into the V from behind with the Iron tilted forward and then pull back over the molten plastic, then push the molten plastic into the V. The flip the well over and do the back side of the seam as well. It's not hard to do, just a slow process of pushing in the filler and pushing the molten plastic into the V and always pulling back toward you. The well took me about 3 hours to finish. I have another Coach that I did this too with the well still in.

Thank you for the suggestions.
I could have been more clear -- it is the rear wheel liner behind the wet bath -- removing it is too large a project for me at the moment. So, buying a new/used replacment isn't an option.
Gene -- thanks for the patch ideas. I have the rear bath wall out and reasonable access to part of the top of the liner now.
Tom -- nicely done plastic welding repairs. Whatever I do now -- I would like to be able to complete a similar repair in the future. Did you consider cutting our the wheel scuff damage and installing bump-ups to give more space -- similar to what the later design allowed?
Please keep the ideas coming.
Dennis

Followed with a coat of Rhino truck bed liner
The wheel wells are made of ABS If I recall correctly. Same as the grill. Both can be a challenge to repair.
I have used a mix of solvent and ABS granuals to make a mix of ABS mud. This stuff is messy, stinks and will form any shape you need, like fiberglass only in the ABS style.
If you have a large hole, make a patch with fiberglas, leave enough room to screw or pop rivit to the good existing material.
THEN after watching MYTHBUSTERS ( no affiliation ) test the incredible strength and abilities of truck bed liner, like Rhino and others, I would definately apply a good coat of truck bed liner over the entire wheel well, including around the edges at the bottom, to seal really well.
after seeing MYTHBUSTERS ( no affiliation ) put this to the test, and see how the truck bed liner kick butt and come out looking the same as it went in, I am going to do this to my rear wheel wells this summer. If you missed the show, it is on the web... you have to see this one to really know the impact of what I am saying and how this stuff held up to explosions, dog bites, and came out the same as it went in, no damage....
With all the talk, over the past year or so, about the damage that occurs when the tires come apart and seeing this show, it might be possible that this stuff may protect the wheel well from being beat apart... A solution has been needed, maybe this may be in the right direction....
