I just picked up a new field box to build for my evening entertainment .The instructions call for using thick 5-15 min C/A but I only have medium 5-15 min C/A and don't have enough time to drive back to the hobby shop before they close.

I was just wondering if this will be sufficient for the job? I don't want to build it and then have it start to fall apart when its loaded up with gear but this is my window if opportunity.

Thanks
