One day I go out to my car and I notice that my there is little bubbles that won't come off my car. The next day it go bigger and bigger. Now its all over my bumper and its like bubbles and its clear and its peeling off. What should I do?

 

I would say wet sand it REALLY GOOD and reclear the piece, unless you want to repaint the bumper

 

That is called delamination. the only way to fix it is to strip off the old paint down to the primer. Have it resealed and reshot. Over time the UVs have broken down the sealer and moisture has now gotten between the paint and body. Even if you get all the flaking off you will still need to take it down and reseal it. Once the sealer goes it will do the same to a new paint job unless it it stripped off.

Best bet it to have a bodyshop evaluate how bad it really is.
