I would like to carbon skin a part and I have a question regarding the 'tack' time before applying the carbon.  The part I want to skin is quite large and has complex surfaces.  I don't want the resin base coat to be really tacky as once you lay the carbon it is very difficult to manipulate into position within damaging the weave pattern.   Therefore, could you lay the carbon earlier, so that the base coat is not so tacky and allows you to manipulate the carbon ? The process states 1-2 hours, but laying on after 10-30 minutes, would this cause any issues ?
