Excellent Product

Very easy to use, smooth flowing when pouring. Very strong accurate shore A material.

to firm for mold making but good for casting

Terrable UV properties. Had a piece of tape holding parts togetherfor about 20 minutes in sunlight (after 4 days of curing indoors). Removed the tape and the area that was covered was 3-4 shades lighter then the rest of the part. Way to sensitive to UV light.
