The coating back in the sixties was Aluminized metal spray coating..It was a white rough finish (like 100 grit sandpaper) It was supposed to slow down the rusting. It didn't stop any heat and it got dirty pretty easy. I had it done on my VW exhaust...it looked good till some simple dip poured beer on the hot pipe...it then had a permanent burnt brown stain. 12 Yrs ago I had headers done inside and out on a 351 mustang by HPC and the under hood heat was reduced by 40 deg c. They still look good today.
