  According to West Systems
  Posted by: pblanc on Oct-10-12 9:26 PM (EST)

pretreatment by flame oxidation of ABS (Royalex) is "optional". The adhesion data provided by West shows little advantage for flame treatment of ABS however.

The first time I bonded skid plates to a Royalex boat with G Flex I used a propane torch to pretreat the hull. Since then I have applied more than a dozen without the flame pretreatment and the bond has been just fine.

It is possible to use more conventional epoxies (like West 105/206) to bond to Royalex, but at least in theory the cured G Flex has a lower modulus of elasticity (is more flexible) than the conventional epoxy, therefore resulting in a better compliance match with ABS.
