certainly did break my heart cause I had all the pictures of me and my bf the last time we saw each other on it, I only had 2 or 3 printed up so I am hoping that some can be saved.
From what I understand if you use it correctly it has the same staying power as the heat set paint, but just like the heat set paint if you use it incorrectly then yea nothing is garenteed lol.
When I first used it I stuck a foot after it had been painted and sat for afew days in hot soapy water and scrubbed it with a nail brush and nothing came off.

The techniques I use some I read on the site I bought my paint from and the rest of it I have just had to experiment with it a bit
I'm sure it will all make sense when I write it up and have the pictures with it

Sound very interesting that's for sure
All the best

Yes it does sound interesting so shall be waiting to read and see it step by step.

Cheers
