It mixes like flex coat -- in a 1:1 ratio. You can also call Anglers Workshop in Washington and they will give you information.

I used Threadmaster lite on my last rod and was very impressed with the result. Time will tell how it holds up.

I even went over the flex coat light I used on another rod because the finish was kind of wavy and uneven. The Thread master smoothed it out and it came out very nice.

I'm sold on this product.

Good luck
