UV rays from the sun are the enemy of bare ABS. Some ABS plastics are UV resistant but none are truly immune to the harming effects of the sun. Paint it with an ABS compatible paint and it is protected. Many paints also cause damage to ABS .... makes it quite brittle not unlike an egg shell. But, use the right paint and it has excellent durability. Good stuff overall but one needs to understand the material.

I am not sure, but I think Armor-all will keep the plastic from getting brittle. At least in all my use...it has been great! Capt,n
