Looks like you are doing a good job on your BR. I also had a hard time matching the cream color on mine. I also did the bondo above the cannon and it has held up pretty good so far.

I also scanned in the compass and cleaned up the artwork, then printed it on a clear water-slide decal before doing my clear coat.

For my clear I used a product called Spray Max 2K (it is a 2 part auto clear in a rattle can). You still need to use a respirator with this though.
