Looks great, I like how you went the extra little bit and remover the recesses in the top of the quarters from under the bed hooks.
Whats the ute in your avatar? It looks like the finished product.

Most painters will warn against painting 2pack over acrylic. It will eventually crack because you are putting hard paint over a flexable paint. In the sun the acrylic will move ever so slightly and the 2pack will have to give somewhere. Will take time to show, but most painter tell that it will show.
Acrylic takes more work to keep looking good, but acrylic clear gives a better shine.
