So I fitted a Jc concepts fox body to my ecx amp Mt. Its a street eliminator project. Anyways my question is what can I use to make fender flars that will allow me too shape it. The amp is wider than a slash with original arms. With drag tires, the wheels will fit under fenders. With the grps on, they stick out fender. I want the fenders to cover both sets of tires for different looks. Originally as going to use plasticweld and got told it won't bond with the polycarbonate. So running out of ideas.
