I dipped a set of ar 15 receivers and a forend for a local gun shop. I used ohw multicam match base coat twn multicam film and ohw 1k clear. my plan was to finish up with ohw 2k clear, but I ran out . I already ordered some more, but the customer is impatient and wants it back asap. he asked if he could clear over the parts with kg gunkote air cure . I know it's a water based polyurethane , not sure if it will have issues going over the ohw. does anyone have any experience with this or know if it will be compatible ?
