First off Freesole works wonder, but those failing to get this to work (even on vibram soles) need to pretty much give up on their instructions.
Myth 1 : Freesole takes 24 hours to cure.
Reality: Freesole in a thin sheet may take 24 hours to cure, but if it has to fill a space or gap of any real kind. think 48 hours. If you are rebuilding a sole on a shoe think more like 96 hours to be safe... those are big globs
Myth 2: Freesole says. wash your sole... sandpaper... then apply.
Reality: the sole needs to be very very clean to get a good bond. it also needs a good flat surface. so wash your sole... sandpaper. score with a little knife to give a good bonding surface (lightly)... and wash again.
Myth 3: Freesole is only good for 2 applications. once when you use it the first time. 2nd when you cut open the tube.
Reality: Clean the tube _BEFORE_ screwing on your cap. otherwise you are gluing your cap to your tube. place tube in a zip lock bag. the next day open the cap again and clean off any missed residue. and you're good to use nearly the full container. remember clean your tube... and
place in zip lock bag just in case...
#EDIT# after an extensive sole rebuild a few tips.
I had to rebuild a good portion of a tennis shoe heel. this was your typical corner wear but it was very deep, making the stacking of thin slices of freesole very difficult. The first time I did this I used some paper to make the gutter, and although it worked, the paper was very difficult to extract from the freesole once dried. The second time I used Transparent scotch tape (which worked fantastically). So if you have to build up something very "big" build a mold/wall using transparent tape, and fill it up until level with the rest of the sole. Let it dry for 1.5 days remove the tape. Freesole will generally puddle up near the scotch tape wall a little bit. if it's higher than the rest of the sole trim carefully.
If it's the level of the rest of the sole, take out some more freesole, and fill it up again. Regardless 4-5 days of waiting are necessary for it to cure to a nice hard material that will be your new heel.
