Versatility is an attribute that can be considered to be synonymous with the 3M Duramix range of adhesives. Ranging from rigid to semi rigid urethane that can be used to create a sturdy bond on fiberglass panels or other semi rigid plastics, to flexible urethane for bonding plastic add-ons parts and more flexible general purpose repair material for flexible plastics, you will find them all here. Most of these strong bonding adhesives sets within a minute and sands easily after 15 minutes; it does not peel back when sanded! You also get to choose a larger cartridge for large scale repairs.
