2kgs in 5 mins? How many arms do you have? :-)) You are right... I need more practice with smaller parts and especially smaller batches. What is your preferred tool to spread the resin? Brush,...

Some people use a MEKP/CHP blend as a summer blend for hot weather - to stretch out the gel time and not have it go off so fast/hot. I think Norox MCP-75 is this... not my area of expertise. Not sur...
