Thanks! Did you mix 50/50? What consistency did you go for? Runny at all? Or just tilt the box and watch it slowly slide around?

I've also thinned body filler down with acetone in the past and it works GREAT. I could probably get it much thinner than I could with resin but I may go with the resin just for the added stiffness.

I just added Bondo to the resin until it created a thick yet decent flowing consistency. Definitely thin enough to flow around the Box when tilted.

Question from the audio challenged. I know you're fabricating a sealed enclosure but is it critical to seal the pin holes?

For sure!! I have seen cones tear from the resistance of having to push/pull air through the pin holes. Even if it isn't that catastrophic, it's going to distort the sound.
