2k thinners will remove light overspray. Do not uses thinners to remove RAPTOR from TPA/ 1K coatings as it will soften the coating.
A coarse compound and mechanical polisher would also remove light overspray from OEM paint work but care must be taken not to burn through the coating underneath.
For RAPTOR overspray over RAPTOR, this will be more difficult to remove. For best result, abrade the area and re-coat.
