First Attempt at Sheet Metal

[truckster]

I started working on putting my Blazer back together, and I decided to repair the fenders that were on it when I bought it. The right side only has a couple of dings, but the left had these holes that looked like a bumper had worn through it at some point.

I decided to try welding them up using 18 gauge sheet metal for the smaller hole and a piece I cut out of a damaged fender for the larger hole. Here's how it ended up. My plan from here is to use a little body putty to finish it off, but if any of the body and paint guys out there think I should do something different I'd like to know.

Thanks.
