Once upon time in a kingdom far far away a company in N. Richland Hills (close N East Mall) called Composites One sold Silmar 41. Then they changed to another brand that worked well also. Then they changed brands again and I did not like that one. I'm not sure what brand they are now selling. You might check and see... ask for a sales rep and give him/her a call. I am one of the many who order polyresin from US Composites. I've tried to find other sources for silmar 41 in the metroplex with no luck. If you find a source let us know.
Do a good turn daily!
