Questions about Cub painting

[thenrie]

It seems that when I see cubs being refurbed, on this and other sites, that folks always advocate stripping the frames, etc down to bare metal. Now, I have not yet painted a Cub, but I have done plenty of automotive work, and in that world, you generally only take things down to the metal when you need to remove rust, bad body work, or bad paint. Normally you would clean up surface rust by grinding and sanding or blasting to bare metal, then prep the surface with a rust cleaner or rust converter, then spray primer over that. Any place where the paint was still tight and good, you would just sand and blend into the stripped places and spray the primer over it, sand some more, then paint. As a matter of fact, paint that is not flaking or otherwise bad, once sanded is a better surface for primer than bare metal.

Am I missing something? Is the original IH paint so bad that it needs to be completely stripped? Or, are we simply overly particular in how we do stuff? I can understand either perspective. I'm just wondering.
