Plated ABS showing untextured patches

[prastaples]

Hi All,

I hope everyone is keeping safe through lockdown. forgive me if this is in the wrong area but it bridges a few areas of expertise.

I am having some knobs plated and lighted textured, but the supplier has advised that they have noticed some patches are coming through untextured and slightly reflective. they have said that they have tried a few things to resolve (unspecified sorry). Has anyone seen something similar , and could you suggest a possible solution.

Thanks
Pete
