I have problem with powermolds. They simply dont seal and feedback occurs and I can not achieve oticon targets (adoption step 3, without teflon tape even 2 make a lot fb). Aids are Oticon Agil power.
They are CIC/MIC stile hard plastic (not acryl) and my audi dont offer any kind of soft silicon or soft coating for plastic one. I have big in ear jaw movement. I believe coating would make it better, because i tried teflon tape and it make things better.
What are my options? Is there any do it yourself coating to order?
Audi will gave me 3d scans if i can find online where to get molds. I saw years ago some firm who make molds, but forgot name.
