hot glue

.... you mean like those hot glue guns melts plastic tubes hot glue ??
are you using it on wood ??...
if so.... I would suggest no....
when its wood to wood... I would suggest using premium wood glue... (those somewhat yellowish color glue....) and put light coat on both sides..
if its wood and laminate... use contact cement... (again.. apply both side...)
if its plastic... hot glue...
and for plastic / metal / wood mix...
and there are a lot of other glues that can be used.... like those "liquid nails"... "gorilla glue".... and eproxy (I believe you mix 2 things and then you have like 15 min before it hardens...)
if I mis-understand you... then just ignore me... but I personally think hot glue gun glue is not suggested for raw wood / wood bond....
