My restoration shop has been more economical and productive because of 3M technology. About the only exception is filler. Here in Central Florida, Rage Ultra mixed with Ultra Extra has made spreading filler in a 100° shop with 50% humidity effortless. 3M Platinum filler is ok, but nothing sands as easily as Rage Ultra.

No Matter how many times I press it out I never get rid of the bubbles. I have the right amount of hardener what else can cause this? I scoop it out with a mixing stick then use a spreader to mix it

There are many reasons why the Pinholes appear. Mixing of filler and hardener in a stirring motion is a common mistake. This introduces air into the filler. Mixing of filler in can is also something that can cause pinholes due to trapped air. Too much hardener in filler can also cause this. To know other reasons that cause pinholes, please watch the video from (05:56). Hope this helps!

A little confused, you say don't apply filler over the basecoat and go and apply filler over the base coat, could you clarify, please

[@3MCollision]

It's ok to have a little filler over the edge knowing that you will be sanding it back off the edge while final sanding and prepping for primer. It becomes an issue if you overlap the paint edge by a lot and the filler remains over that painted edge once you apply primer -- that's when it traps in the styrene, which will shrink back later. So it's ok to overlap a little as long as you sand it off before priming. 👍 Some repairs are too small to completely avoid the painted edge when applying the filler.

You should be feathering out bare metal all the way around you filler after sanding so that little bit of filler will be gone
