im doing resin pinlines using rr epoxy...as ive heard you mix the pigment with the hardener then mix with resin...so heres the question...do you add more hardener to make up for the amount of pigment youre adding to the mix or still stay true to the 2:1 ratio plus the amount of pigment?
By all means, never deviate from the prescribed ratio. Never, ever. Mix small batches by weight - 100:45 resin to hardener. I measure my hardener, calculate my resin, mix the pigment into the hardener, then add the resin, Add. F, X-55.
