The cap is abs Ken. Almost any type of epoxy or resin system will bond with
it. After fooling around with a few expensive 2 componnent cartridge type
automotive adhesives on the front cap i decided to try the abs cement and
fiberglass cloth method someone mentioned here on the rear. Since i was
planning on covering my caps with fabric when done a level smooth contour
was not necessary. The abs cement and finerglass mat method was by far the
fastest and easiest method i tried. If i was to paint the cap after the
repair i would use the abs cement to get the mat saturated and adhered to
the cap and re coat once fully dry with a brush in order to get the build
needed to bury the mat completely and smooth that with some sandpaper to
contour
