Thats correct if there is alot of tiny bubbles its because they didnt clean or prep it well. There could also be dust attached to the tint itself. I had alot of dirt on mine and made them redo all the windows even though they didnt want to do the drivers side. If you really want to know post pics up and we can say alot better than just guessingthe little microscopic sized bubbles are just were there is dust or something tiny underneath the tint. as far as bubbling goes, that is not normal. discoloration is normal for up to a few weeks. it takes some sub to go away.
