3M 4200 usage
Great Product. My secret. Sometimes you will need to remove a fitting. So the 4200 is just easier to use. I use a thin amount on all plumbing fittings. It helps with the seal and boat movement.

excellent produit technique et de qualité.
excellent produit technique et de qualité. J'ai collé des ailerons de stabilisation sur des kayaks en plastique. La durée de la colle dans le tube après ouverture est de quelques jours et non de quelques heures comme indiqué

Great adhesive for fibreglass
Great product ! Easy to apply. Used it to repair a fibreglass trailer. Results were better than expected. Easily sanded off the excess adhesive.
