I just got done powder coating the A5 and the M98 and they looks sharp. There a nice flat black and I really like it. So I voted flat black. For touch up I bought the flat black camo paint from Wally-world (Wal-Mart) and its a nice match to fix the minor problems :-)
I think there is a gent on the fourm called wookie that has examples of other paint jobs he has done as well as walkthought on how to digi paint the marker and a few other patterns.

P.S To touch base on what rx78gp02 posted about filling up the plaque area. I had to jump over to Model98.org - The Tippmann 98 Resource. as I read there before on there painting and milling of the M98. There was a post that the use of JB weld on such a large area would look bad in the end. Not sure why. But they suggested the use of a two part bondo type product found in auto stores. Fill the gap, let it dry and sand, sand, sand away the extra bondo. Prime then paint away. This coming winter I am going to doing this and filling in the milled text as well. Need to find something that can withstand high temp as I will be powder coating the marker again.
There is also a gent called airhog that if asked could point us in the more correct direction of filling in the gaps on the marker.
