Need input about step-prime


Recommended Posts

Posted

Just want some opinions on this. The prime I am using is a 2 step system, KP hot prime first, followed by a bp+mgal mix on top. My question is about the BP+MgAl step. The formula just calls for lift-grade bp + 5% MgAl. Well, I also added 5% silicon, and 5% Diatomaceous earth. Being that silicon is also a metal, am I wasting time/money putting the silicon in there since there is already MgAl in it? And what do you think about the DE? I would think it could only help, plus I have a 50 pound bag of it. :) Thanks in advance.

If the bp mgal prime works. You don't have to put extra silicon in the prime. Just use silicon ore mgal.

I use scratch mixed BP + 3% Mg/Al + 3% SGRS. For my final prime. The silicon and DE probably aren't really needed . . .
