BACK Mix Filler & Reduce Pinholes
Many of the pinholes we deal with come from the way that we mix the filler itself. A little technique... Take the spreader and form it in a sort of C shape position, place it perpendicular to the mixing board and make a figure 8 sign. You can see how the activator is picked up and move directly into the filler. This doesn't introduce any external air into the filler. Do this for about 30 seconds, then pick the filler up, press it out. If you still see the hardener through the paste, simply pick the product up again, run the figure 8 for another few seconds. Then pick the filler up and press it down again.
