I don't have any pics where you can really see the channel. And I sold this truck a while back. But, the channel repair wasn't really noticeable to an untrained eye.
Here's one pic. I would suggest, if you're gonna do it don't use Bondo because it will crack when applied thick. I used Duraglass first, then feathered it with Chromalight. My channels were just in such bad shape, this was just an "easy" fix since I painted it flat anyway.
