I ordered some paint from LRS late model restoration ( a mustang supply company) the grey color is called opal for 93, I don't know if they have the mocha you speak of, but first clean the surface with acryliclean or some other degrease/de-oil cleaner, once that is done you need to take a very fine grit sandpaper, 1500 (maybe a little less like 1000) grind the loose mocha off,if not it will bubble and look like ***, but get that off, just work the edges of the peeling down so they are less noticeable, kinda blend it, go into the painted area a bit, don't do it so much it will take the texture off, but enough to blend the drop-off down. put some acryliclean over surface to prep the surface once again, just spray it and it will look new! I did mine, and she is dead sexy now!!!!
