Light weight conical mirrors: re-coating???

Hi all,

Light weight conical mirrors are becoming popular. One question I have is when it comes to re-aluminizing these, won't there be problems with the epoxy used in the anchor points? Re-aluminizing happens under vacuum, and as the epoxy will not be able to be removed totally, the expoxy will be continually contaminating the process. Is this point being overlooked, or have I missed something? Epoxy quality also varies tremendously too, and is not the safest material to remove too.
