The down side to powder coating is it can’t be applied outside of the confines of a paint shop complete with it’s curing ovens spray booths and so on.
Yet so many times the customer calls to say they’ve chipped, scratched, marked, dropped the item you’ve coated and they want you to mix them up some touch up paint to enable a hashed repair job.
Powder Colours can match your powder coating in an aerosol paint weather it be a box of 6 or just the one. This allows your customer to patch repair the damage with a coating that matches the one you applied, dries quickly and can (with a degree of skill) look almost invisable
Some metallic finishes can not be matched accurately due to the different way metallic pigments behave in wet paint as compared to powder.
