Haven't tried the Ultra Cast yet but it has arrived. I have no doubt about how fabulous it will be based on reviews I have read, here and on other sites.
The customer service is AMAZING! I ordered at 15.33 on a Friday afternoon and by 15.44 I had an email with a FEDEX tracking number to say that my resin was coming the next day!! Never had such a fast response and it arrived as promised.
Whatever you guys do, keep doing it! 5* service :)

Im loving Ultracast. Hardly any bubbles and they were easy to disperse. Heat resistance is fantastic and no odour. I like the different shape bottles for A and B. Well done again Elichem.

Tried out EliChem’s Ultracast for the first time last night - it was already ready for demolding this morning and gives the most bubble-free finish I’ve ever seen with very little torching!! Super impressed

The heatresistance is great, no sorrows making window-pictures anymore; nearly no bubbles, uv-protected (no yellowing) - real great!
