Well, not having re-coated the PDMS layer in a resin tray I’m not too sure of that. I feel the silicon glue is a good approach and i will try that on new tanks for a bit. I put two new tanks in December 4 on the December 15 one of the tanks had already started to peel along the wiper edge. I bought a tube of the 100% silicone clear glue and will try that.
Iv’e felt for a long time that one could take an old resin tray and peel the PDMS layer out of it. Then also remove the clear piece in the center leaving just the orange tank frame. To this I would add a bit of an edge, 3/16" square styrene square solid rod around the top edge to reinforce it. Then use this as a master to make a silicon mold. The trays don’t have to be orange. Only reason for that is to protect the resin if you leave the trays out in the light. Best to put them back in the box if they have resin in them anyway. Then cast the tray in clear resin. Add the clear window back and you have a much less expensive tray. Just an idea. Even at the current price the resin trays aren’t that expensive so this is just an idea.
