Nope - get some pics and I will give you pointers on how to do it. Mig welders are perfect for filling holes but I times I do TIG them. I have gotten very good at welding up rust holes with the mig - you zap it till you get a ball stuck and then use the ball as a heat sink and work around the hole. These were rust holes I stitched up with a mig.

That's a bit further from a solid edge than I anticipated. There is some risk of warping. I would use a heat sink compound such as this one (this is the one I use - its reusable - just keep it wet)
To weld it, I would go down one heat setting than what is called for. Need to keep an eye on it - may need to go to rated heat.
Trick is to just zap it. Zap an edge, let it cool for a second, then zap right next to it using the first ball as a heat sink. Keep going around - you can fill about 2/3 of the hole and then finish it up - very small circular motion. If you are concerned about burning through then go all the way around the hole before you finish it - the welded part is much more difficult to burn through. It is pretty amazing how big a hole you can bridge with the mig. Certainly when you have about 1/8 inch hole left just finish it off. If you do it correctly after grinding all you will need is primer. Grind with a 36 grit sanding disk, although 24 grit can also be used. I use a 5 inch disc. Use 0.025 wire - thicker wire (0.030) can be used but its not as good or easy.
Yes white top, white interior, Turbine bronze, I like the look and I have all the trim plus some and a shame to leave off but car will be outside most all year round so I don't think it would be a good idea to put one back on.
