I will agree with you that acrylic is definately more forgiving especially for the inexperianced painter, but dont be fooled you can slice and buff 2 pac quite easily, as a matter of fact i did my Hilux that i panted in 2 Pac just last night, sliced it with 2000 grit wet and dry and buffed it, paint looks flat (not peely ) like glass. There are differences in the paint systems you use and some are harder to work with than others in 2 pac and can require more work. The advantage of 2 pac over acrylic is it dosent lose its shine anywhere nearly as quickly as acrylic there for less work to maintain the quality of finnish. You are right though alote of people still use acrylic for show cars but again this is great if you have the time to keep up the polish and keep it out of the sun.
I can prove this theory quite easily My sister has a car that was factory painted in acrylic 91 model and was involved in an accident 3 months after she bought it. the repairs were painted in 2 pack and for the last few years you can really tell the difference as the acrylic has faded far more, i give it a buff looks good for about 3 to 4 months and then sh#t house again. 2 pac paint will outlast acrylic in NORMAL everyday circumstances by far with far less polishing needed.
