I keep meaning to post pics, but: I've since done two more enclosures where, before applying the actual decal, I first applied about three coats of Dishwasher Safe Mod Podge (DSMP), waiting two hours between applications, and then baking for an hour at 200F. The difference between these and Andromeda above is that
I didn't sand before applying the decal. I then baked with the decal film for another hour at 200F. The two enclosures where I used this process have come out perfect, 100% image transfer. After it's cooled completely, I then apply another three coats of DSMP (two hours between coats), and yet another hour bake at 200F. So the total process looks like this:
- Clean enclosure thoroughly, wipe down with rubbing alcohol
- Apply three coats of DSMP, letting air-dry at least two hours between coats
- Bake for one hour at 200F, let fully cool
- Apply film-free decal using DSMP (same process as if using the Sunnyscopa transfer agents)
- Bake again for one hour at 200F, let fully cool
- Carefully, slowly remove decal film
- Apply three coats of DSMP, letting air-dry at least two hours between coats
- Do a final hour bake at 200F
