If mixed with clear epoxy will the epoxy harden with the same crystal clear finish?

Sorry but No. The filler is white polyethylene and will cure white when mixed with clear resin.

How does this affect pot life/use time?

It doesn't but they type of epoxy does

Does this thickener absorb moisture? I'm worried of bubbles in the resin.

Bubbles in resin can be minimized with alcohol (sprayed over areas) or by heat (can ise a blower) just be careful, small amounts

Very effective...stirs in well with the epoxy, has no odor, and doesn't seem to affect the curing time, or noticeably add to the volume.

Although I did not use this as a covering, I did use it to glue 32 ga steel to a structure with both a positive and negative curve. Held in place with a sandbag, it seems to have worked quite well. Of course it’s always difficult to give initial quality on something when that quality will only become apparent after at least a year.

The product did what it meant to do. However. It turns the clear epoxy cloudy or white if you use too much.
