2 pack would be easier cause you only need 1 coat (the fumes are toxic). Acrylic you need several coats and then a clear coat to make it glossy. 2 pack is stronger to scratches so id go with 2 pack, and i believe it doesnt need thinners whereas acrylic does. I DIY'd my car using acrylic paint and it turned out pretty good still strong, check out my build thread
