Spreading Powdercoat

Have any of y'all had a frame Powder coated and then later on spread your rear triangle from 120/126 to 130? Did it cause any imperfections in the powder coat? I'm thinking it shouldn't be a problem at all since we do it with paint all the time, but I just wanted some real world examples.

Not sure if it is affected by age like paint, but in the body shop industry they do not expect dented metal to retain paint without cracking past 5 years since new. Powder can however soften a little with heat, so you might get it to 'bend' a little better by warming it with a hair dryer (not hot) first.

That makes sense, since it's plastic, which flexes more easily when warm. But seriously, at room temperature, I don't see it being a problem, either. You're not bending those chainstays very far, after all.

Spread it, no problem. You're overthinking this.
