How did he get it so smooth? Is it just a matter of sanding? Is there bondo involved? One of these days I'd like to weld up a cowl. That would definately seperate my car from the other Caddy's on the street.
Wasn't there one on a cobbled-up pink Fleetwood wagon? IMHO, the look could be carried off with about a 3/4" tall cowl type, but anything more would seem to require a batch of other body mods to keep up.
