Not a problem dave.

I've used the Bulldog before, on a couple really "rubbery" Banshees. You spray it over the cleaned and prepped plastic, then you can also mix it into each coat.

(1)- It is a plastics adhesion promotor....(smells like new vinyl, so I'm guessing it used a plastics solvent to "bite"),

(2)- crosslinker for intercoat adhesion,

(3)- and a flex agent....(I've seen pieces bent to about 30 degrees, which makes me pucker, but no problems yet.)

I don't know how flexible the Mule parts are, but I only used it for the initial "plastic to paint" step on this Rhino, since the plastic parts are pretty stiff.
