From the car nut/mold engineer with 20 years experience sitting next to me, definitely go for the polyurethane. Broadly speaking ABS is more sensitive to UV over time and stress cracks from vibrations. Only time you need ABS is when you need a hard surface otherwise PU is more durable. __________________ My Former Rides 1999 318ti Alpine White, Cali Roof, Dinan goodies 1996 318ti Hellrot California Edition |
