Yes I can recall 3 members that have done it (can't recall their usernames) 2 of them were successful 1 of them wasn't, the guy who wasn't happy with his was an Aussie, I think he had 30% and complained of hardening.
It all depends on how much you have remaining, if I were you I'd try remove or reduce what you have left, you could start with dmso. I know Morgenstern is able to get rid of lumps of fat using a non surgical technique so theoretically might be able reduce it.
I definitely wouldn't have it if you have more than 1/2 half Inch of fat remaining.
What ever you do, let us know how it goes.
If you add PMMA with your existing FFT, as the fat absorbs more I would guess it will create dips in the PMMA and you will have to go and get more PMMA and the results may be very uneven, of course Dr C will know better, send him an email even if you don\'t use him.
If it was me, I\'s wait till all the fat is gone or have it removed as suggested then add PMMA to ensure best possible outcome
