Don't think Krown will do much for parts that see a lot of heat, like the exhaust manifold heat shields.
I've never had a problem with any of the heat shields "rotting off" on my F150's, but doesn't mean it can't happen I suppose.
Seeing as you're outside your warranty, (mileage wise), you've got a few choices.
Choice #1 - Do nothing. Probably wouldn't be a bad idea to remove it from the engine mount though, just in case it decides to drop onto the road and bounce it's way from front to back as you're driving.
Choice #2 - Buy a new one and throw it on. I can't imagine heat shields are going to break the bank, but might be a pain in the ass to install.
Choice #3 - Depending on what sort of relationship you have with your dealer (if you have one) , drop by and ask them if they've seen much of the problem.
Who knows....maybe there's a TSB out there, or they might be willing to work toward a solution.
Doesn't cost anything to ask, but I don't think it's anything to get too worked up about.
