Deanski,
I'm not entirely sure why you are harping on Lexus soo strongly. Sure the SC430 is an expensive and awesome car but at the end of the day, Lexus are trying their best to keep you satisfied "within reason".
The facts above don't necessarily stack up in your favour and you're lucky the dealer is being soo understanding. I actually sympathize with Lexus on this one:
1. I would be responsible to have the glove removed and re-applied at MY COST! ..... WTF???
Armourglove shouldn't have applied the treatment if there were paintchips without notifying you in advance. If you approve the application, then why should Lexus pay to have it removed? It was a bad judgement call either by Armouglove or yourself NOT LEXUS. They have nothing to do with this side of it.
2. "Now, I assumed that ALL repairs were made, and had no reason to leave my office, drive all the way to the dealer to inspect the car. After all, it's Lexus"
Never assume anything

The fact is, they simply could have missed one or two. So it goes. It's your responsibility to ensure the corrective actions Lexus took met your standards.
3. Amourglove should never had applied the treatment the second time if the chips hadn't been filled in!!! - Granted, I may have misinterpreted the actual sequence of events so the second application may have never taken place???
4. "The dealer is willing to repair the chipped area again, and wants to keep the car several days for any paint to cure (were talking a chip now). "
Very professional and reasonable on Lexus' behalf.
5. If the paint wasn't fully cured, that is your issue not Lexus. REMEMBER: This is an aftermarket add-on, Lexus shouldn't and has absolutely no responsiblity for it. It is YOUR responsibility and that of Armourglove to ensure the proper application.
------
Take a step back, look at the situation and you'll realize Lexus have done their part. If you hadn't applied the Armourglove in the first place, you're dissatification would have been needing to drop off the car a second time to complete "free" repairs which Lexus has absolutely no obligation to cover. I bet you would have lived with that. Sure it sucks but hey, it's free!
Stone chips are a fact of life that we all must live with. It's not Lexus' fault, don't drive the car then if you don't want to live with the driving hazards that are out there.
If Acid Rain damages your car, are you going to go after Lexus for a full repaint!!!
A stone breaks your front glass or a fog light, are you expecting Lexus to cover that as well???
Let me know if you file a more formal complaint with Lexus and I'd be glad to write an opposing viewpoint letter and forward it to them in support of their position. It may be that Lexus need a better customer support manager to respond in a stronger way highlighting where you may have went wrong in your decision making tree and the fact of adding on aftermarket accessories complicates their ability to serve you.
Note: I do not own a Lexus. I just don't like a car company getting slammed so strongly on a public forum for what is probably an owner issue after they've been professional enough to address the concern over and above what would is deemed normal warranty coverage.
This is no way meant to instigate a flame war but only to present an opposing viewpoint.
