No dout, seems like you'll lose paint on any gutter if you leave a chemical like that on to long. We spray bleach first on really bad gutters, then we use Gutter Zap applied w/ a conforming pad -- note that the dwell time limit for the chemical left on the gutter is super important for fantastic results.
