Thanks Malleus, for both the "Love", and the unsolicited opinion.
I agree with both of you comments about power coating (pc) and throughout most of my life have stayed away from it, but ...
Backstory: I had a new bumper for I'm no longer sure for what, when I was much younger - it took a lot of my disposable income at the time, and after several months the pc was coming off in good sized flakes, almost sheets, peeling back away mostly from sharp edges, and this wasn't caused by impact or scraping. And this experience has repeated for me over the years - even in the last several years, some of my son's new landscaping accessories, like leaf blower holders, had the pc fail, and again, not due to impact.
Then, in roughly 2018, the wheels on my 450 were in bad shape, but I didn't want to put money into new wheels, and prepping the aluminum was going to be tedious, largely because I didn't have a blasting cabinet to help prep / clean them for paint, so I started looking into options and called several local shops, for both blasting (and I would paint them myself), and for pc.
The one pc shops agreed with many of my concerns and also discussed why these concerns were largely not valid with his process - preparation is 90% of the battle. He also seemed fastidious and knowledgeable, and would both pre-bake and blast the wheels to be certain that any oils were burnt off and to assure he had a proper surface for bonding. He also uses a primer pc for a stronger adhesion, and then a topcoat pc, which also has strong UV inhibitors. On top of all of that, his price was also about $10 higher than it was going to cost to have them blasted, so we had him coat them. For the curious, they were $60 / wheel. And these wheels are still as good as the day we installed them on the LX450.
Then about a year later, we again trusted him with the wheels that are now on the 65 Carryall that I shared back in post
#185, and these too came out fantastic and have held up well, even if they haven't seen any abuse.
After starting to trust his pc work, I build my son a bed extender and ramp system (pic below, so you can see what I'm referring to) for his business pickup in the spring of 2022, and if you ever tried to paint expanded metal, so it won't rust, it is not easy. And all of the steel used was hot rolled, so adhesion would benefit greatly from blasting to remove the scale, so we again took it to be pc'd - all of it for $380, so it simply wasn't worth my time to blast / prep and then paint. It too has held up beyond expectations - this ramp system has seen 3 year of full time service, running 30", 48" and 52" mowers in and out, plus all of the other full-out work-truck activities, and still today, nothing has started to peel or rust, and even hard impacts have not caused any chipping. There are several scrapes that cut through outer coating, but not both. This is the toughest powder coating that I have ever seen. I also suspect that the fine powder, being drawn in electrostatically, is slightly better at penetrating tight areas.
None of this is to say that your point about touching up pc work is invalid, but so far I have had no reason to - and even if I scratch a wheel on a rock, it doesn't seem to want to chip, in direct opposition to all of my previous pc experience.
And my son would likely attest to being tired of hearing me comment that I can't believe how well the pc has held up. And despite all of this, I may still paint the fifteen52 wheels because I hope they will see more action out in the desert. (This post likely wins the "too many words" award, or "I just don't care award",but here you go.)
