First time with Uni-Mould. I made enough resin to do only two layers of 450CSM, Mistake in calculation, for a hood that I am building. That same miscalculation meant that I did not have enough MEKP on hand to make enough for the final two layers. Can I come back and add the additional reinforcement a week later? Have to travel and ran out of time. This is not a production mould. I hope to get two good hoods out of it.
