pingulusan

I’m not finding a widely recognized definition for “pingulusan.” It may be a regional term, a misspelling (for example, of pengulusan), or a newly coined concept. Could you specify the language or region, the field or discipline, or provide a brief definition? Once I have the intended meaning, I can draft a concise, neutral wiki-style article (under 300 words) in plain text. If you meant a general topic like finishing or polishing in crafts or manufacturing, I can write a standard article on that subject as well.
