I think this might be more of a technician issue than a resin issue. If you go with one of the top resin suppliers you should be fine as far as product quality is concerned. There will be some variances from brand to brand though. Stay away from the generics as the quality might not be consistant. I personally use Delta Kits Resin only.

Tip:Make sure all the air is evacuated. Sometimes a small air pocket might be hiding just under the injector seal or the pit resin might be airated when applied.

Hope this helps somewhat.

Pay it foward,
