Thanks guys. I wonder if todays 2024 T3 has a thinner cladding than the aluminum they used say 30, 40 years ago? Countless vintage trailers have been polished up with no problems, but I have heard of stories of people stripping and orbital sanding the clear coat and then had accidently sanded through the aluminum cladding as well. I'm more concerned with the removal of scratches than the removal of clear coating. With the currant cost of aluminum and modern technology I can see how this cladding has evolved as a much thinner coating. If I go to the expense of a new skin, I would like to know if I used the best possible material. P.S. I'm thinking of replicating a 1948
liner but only longer, so I don't think I'll have to form stretch any parts.
