As far as I'm concerned on the powder coat issues. I have had excellent luck on the durability. I have been flying the slug for almost 9 years now and it still looks like new. That being said, like others Tom and all have stated, I needed to bring the fuselage in for a touch up after it was first done. Yep not getting in to the clusters and in other areas dry spots. The guy wasn't very happy to redo. The second time he poured it on. Real thick. Not so good for weight savings but looks great.
If I ever did it again... I wouldn't powder coat for the same reason others have said again. If you want to weld another tab or

? you would probably end up with a big mess... Torches and plastic.. uhm. Also some say again that it could possibly hide cracks.
Looks great, holds up well in my case but next time I'd PAINT...
