Paint help quick

If your base is bubbling you need to stop right now. Something is wrong. The bubbles are just where it's letting go right now, the rest of it may be flat but have little or no adhesion.

If it was just nicked up in places, you could have just feathered the chips, hit those areas with a little rattle can etch primer (quality brand like SEM), scuffed the engine compartment, blended in the base (or base the entire thing), and re-cleared.

Do you have a water filter on your air system?
