Hi all, I have made a few pieces of furniture using the glass cast 50 epoxy. I have managed to sell them to a customer too which is great news, however, I am a little worried about the longevity of the product while in use. I have managed to scratch it quite easily and being a clear cast (no pigment tints) scratches are quite noticeable. I obviously don't want for them to yellow over time , so I was wondering if anyone out there has tried coating them in something like lacquer, and if so which product? 
I'd love for them to be a little more scratch resistant and UV light resistant before they leave to the customer ... Any ideas?
Thanks very much for any help

I am not aware of any surface coatings that improve scratch resistance.  Once the resin has had its full cure (7 days) it should be as hard as it can be.  The first week and especially the first few days, the resin can be more vulnerable to scratches as its hardness continues to develop for around 7 days.  If the resin stays quite soft, it could be a very slight measuring error.  If the mix ratio is slightly out, then it can mean the resin cures softer than it ordinarily would. 

GlassCast already has a high level of UV resistance and as such is not likely to noticably yellow in indoor applications.  However if you used it outdoors, then a PU lacquer or similar might be beneficial to improve UV resistance and slow down yellowing.
