Glue - Advice

Great Bonding Glue. Must use special dispensing gun. Great gap filler. Mix in very well vented area (yes, really). Working time seems to be less than advertised. Glue expensive, gun expensive, but otherwise great.

Expensive but worth it

Used the MA425 to bond a deck to hull. Tests prior to actually bonding the deck proved this stuff sticks. To get it apart, plan on destroying the part. My test was on fiberglass foam core panels, the glass had a peelply finish.The dispenser gun is solid and works very well. I had no problems at all with the stuff, not a single misplaced bead. The stuff mashes well and does not require much clamping pressure. You might need spacers to keep it from squashing too thing but it won't run on vertical surfaces, it stays where you put it.
