Default Through-glass antenna power limits

(I realize that a through-the-glass antenna is less than ideal.
Nevertheless, that's what I have to use in my situation.) The one I
have is for 2 meters (NOT dual band), and the label says up to 50
watts. I have an Icom IC-2200H, which has a maximum of 65 watts
output.

What bad things may/could/will happen if I put 65 watts through the
antenna?

Thanks!

On a personal note, I have a dual bander through the glass mount. I
use a 857 yeasu and managed to fry the matching unit on the inside of
the car. From what I saw when I repaired the unit was the main
resonating cap is a brass screw in a brass tube with a 'plastic'
insulator in between. With the wattage I get from the 857 the plastic
dia-lectic melted. I replaced the cap with a professional glass 0.5 to
5 pF trimmer cap and it has worked fine ever since.
