The instructions for mixing the primer are to use 2% MEKP catalyst, the scales give weight in grams and mixing 75g of primer would require the scales to be accurate to half a gram to measure 1.5g. Is the percentage critical or would 2 grams be OK.I thought the Catalyst bottle was the answer but it measures ml not grams so how much does 1ml of MEKP weigh?
Am I being confused or am I missing a trick?
I do not want to mix large amounts as I am making Brake cooling ducts for my race car and they are not big like a car hood/bonnet.
