Always getting this sort of patches ..3rd time doing it..following strictly on the instruction..leaving 24 hrs plus/minus aft every coating...pls advice??

Hi,

Could you give me a bit more information about what materials you're using? I gather you're skinning a part using epoxy and carbon and I can clearly see from the photo that there is a contamination issue with the resin (those 'contour' lines are a classic sign of a resin that is either not suitable for skinning with or that is contaminated somehow, most commonly by moisture absorbtion or by incorrectly mixed resin/hardener.

Please confirm what resin you're using, what ration you're mixing at and what room temperature you're working at and I should be able to identify and solve the problem for you.

Best regards, Matt
