Hi,
Fun job, I have to do the same thing to my 81, Ricambi has the fender lip repair panels for sale but I cannot find the outer inside wheel housing repair panels anywhere. Let me know where you finally get them. My e mail is

Good luck with your project. I have already cleaned all the underside of my body down to bare metal, POR-15'd it and then used european texture undercoating over the whole thing. This weekend coming up, I am painting over the undercoating with POR 15 hardnose paint, a 2 part epoxy paint, in the same color as the car. I have to do the metal as soon as possible wherever I strip before rust starts. I am in Vancouver, BC where there is just too much rain and my garage is not heated.
I was lucky, there was just a little rust in the front floor that I welded in some new metal and the rear arches is the worst on the whole car.
Thanks, Rick
