Smooth-On VytaFlex 60 - Liquid Urethane Rubber - Pint Unit

Easy to use. It take a long time to set so it is perfect for achieving small details in thin parts. It is very pliant and flexible when fully hardened. I bought this to try it out and I am happy with my results.

They wanted $250 for a set of polyurethane motor mounts for my mk4 vr6 so I decided I might as well try my hand at fabricating my own. This stuff was super easy to use and the end result was better than I could've imagined. Extremity ridged poly put my motor right where it belongs and has kept it there without fail for a couple of weeks now.

If you can get it to release from your mould its great.

Used to strengthen a stock motor mount. Things worked well and were straight forward. For my needs this was a great product to have.

Very high quality products

this one also a waste but got refunded

This mixture did not degas well so l had tons of bubbles. My part doesn't have to look great so l'm ok with the bubbles but would not use this for cosmetic parts. The biggest issue is that the bottles were not 16 ounces each. I measured my mold and somehow need exactly 8 ounces per part so this should make 4 parts. This made 3 part because on had 15 punces and the other only had 12 ounces. Apparently their quality control is lacking badly.

It is important to know the shore number for flexibility or rigidness. For us the lower number (20) was like fishing lure material, too flexible for the diameter10 mm. The higher number (60) was very much more rigid but still very flexible for the diameter. We also like the capability of attaching more silicone without worrying that it will come off. Make small batches. Any leftover can be sliced off and mixed in with a liquid batch without worry.
