I`M WITH MOST GUYS` AND YOUR SELF. MIX JUST ENOUGH 5 MINUTE epoxy TO SECURE YOUR DOWEL.LET CURE.SAND FLAT. THEN SEAL WITH EPOXY REDUCED AT ABOUT 40%OF YOUR ALREADY MIXED,2 PART EPOXY THE WEIGHT ISN`T MUCH OF AN ISSUE HERE BECAUSE THE ALCOHOL ACTS ONLY AS "VEHICLE"TO DRIVE THE EPOXY"DEEP"IN TO THE GRAIN OF THE WOOD. IF YOU REALLY WANT TO BE PROFESSIONAL.LET CURE,SCUFF SAND WITH 22O GRT.SAND PAPER, AND APPLY ANOTHER COAT OF EPOXY MIX AT 50% A SECOND TIME.REMEMBER THE ALCOHOL WILL EVAPORATE AWAY AND WILL NOT ADD TO WEIGHT OF THE EPOXY AT ALL.ONE STEP FURTHER WITH A QUICK COAT OF PAINT TO MATCH THE FUSE.AND IT WILL BE JUST SHY OF BULLET-PROOF AND LOOK REAL NICE TO BOOT!!! FLY for NOW !!!!!! DAVE B. p.s. use an appropriate size paint brush to really "push" product in to that wood then you can clean brush with alcohol and use that alcohol to"reduce"the next batch (2`nd coat)of epoxy that type of fire-wall job will likely outlast the plane
