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.
