Blooming/watermarking to paintwork

  1. My model of MX-5 is: __2008 NC
  2. I’m based near: __Ipswich
  3. I’m looking for technical help or recommendations on: __Blooming/watermark to paintwork

For a 14-year old car the bodywork on my NC is generally quite good.The exception is an area of blooming/watermarking around the near side headlight which appears to be beneath the final lacquer coat.I assume the only way to deal with this is strip it all the way back and re-spray?
