Sunnyscopa Film-Free Laser Jet Waterslide Notes for New GW1-PRO 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?

Thanks! I haven't tried transferring to bare aluminum, only Tayda powder coated enclosures. It's important to first prep the enclosure surface. I do a quick wipe with alcohol soaked paper towel beforehand. The last few times I used the film-free decals, I went to FedEx Office and used their laser printer/copier. I've had to experiment with the paper thickness settings to get the proper amount of ink. There's a Zen to how much Mod Podge to apply; too much, and it's messy and doesn't transfer properly; if you don't use enough, there's nothing in between the enclosure and the transfer sheet to grab onto the ink, plus it's hard to slide the sheet into proper position. Also, I try to leave somewhere between 1/8" to 1/4" of the sheet overhanging towards one end of the enclosure so I can grab it to peel off.
For the transfer process, I hold a hot blow dryer very close and move very slowly for about 7 minutes to transfer the image. The plastic gets kind of melty, but it's okay. I wait about half an hour for the enclosure to cool (very important), then carefully peel back the transfer film. Afterwards, I use alcohol and folded paper towels, sometimes Q-tips, to remove any excess glue. Once you're satisfied with the cleaned up enclosure, it's time for the final setting. Since I've been using Tayda powder coated enclosures, I only heat to about 240 degrees Fahrenheit for 30 minutes in a dedicated toaster oven for the final setting. Any hotter will mess up the powder coating. You can go a little hotter on bare aluminum.
Hmm, that's interesting. It doesn't sound radically different than what I did. You used a hair dryer, where I used a toaster oven, but unless you managed to hit some magic "Goldilocks" temperature, I don't feel that's a major difference. (And as a matter of routine, I always let the enclosures fully cool after any heating/drying step.)
However, that you haven't done bare aluminum may be a clue... Sunnyscopa themselves have different products for smooth (W1+) and porous (W2) surfaces. And in my trials with the new GW1-PRO glue, I've had pretty good luck on bare aluminum but not on coated enclosures. So my working theory is that all these transfer agents, including Mod Podge, have varying amounts of sensitivity to the target surface. I also get the feeling that this Dishwasher Safe Mod Podge is intended for use on things like ceramic mugs - presumably much closer to coated enclosures in terms of smoothness, compared to raw aluminum (raw aluminum that I sanded with fairly coarse sandpaper).
I'll have to try Mod Podge again on a powder-coated enclosure. I hope it works because I'm almost out of the OG W1+ glue, and the GW1-PRO hasn't worked reliably on powder-coated enclosures.

I do believe there may be something to the hair dryer treatment. The hot air is very direct on the transfer sheet. I can't actually see it happening, but I'm pretty sure the direct heat is releasing the ink onto the enclosure. I've had some failures with the hair dryer method, where I wasn't holding it close enough and/or moving too fast, but after some trial and error, I believe I have a fairly solid methodology to it. I always have some acetone ready for the inevitable screw-ups, but most of the time it turns out decent. You may want to give it a shot.
I used to use a hair dryer back when I first started doing this (with the W1+ glue). I switched to the toaster oven just because it's easier (literally set it and forget it). What do you think about a heat gun versus the hair dryer?
