I actually like the Mod Podge Dishwasher safe glue better than the original glue. There's still a learning curve with the whole transfer process, but it seems more forgiving than the original W1+ glue.
So I bought this dishwasher save Mod Podge, and tried it with the Sunnyscopa film-free laserjet paper. It didn't really work, I got less than 50% transfer of toner to the enclosure. I was using a bare aluminum enclosure that I'd sanded with 180 grit sandpaper, using an orbital sander. I followed the same application process I described here, using the Mod Podge instead of the Sunnyscopa transfer aid. I did a 15ish minute drying in the toaster oven at 225F.
After that failed, I re-sanded the enclosures and used the GW1-PRO glue, and got a perfect transfer. (The GW1-PRO has generally been pretty good for me on bare aluminum enclosures).
Your pedal looks great, you clearly got 100% transfer. Did your process differ compared to what I described?
