Should I apply pattern coat primer on each part before I glue the parts together? How many coats of pattern coat primer does it looks like I will need? It should be quite straight when Iam finish with the sanding. I plan on applying a coat of hi gloss pattern coat before polish. Should I apply the pattern coats with brush or gun?

Number of coats will depend on the finish you achieve on your first coat, but key between coats if you need to build up a decent thickness of coating to flat back. Spraying will give you a better finish but if the part's not overly large then working through the brush marks shouldn't be too bad. It's likely that you'll break through to the pattern surface at some points, so might be best to re-coat only when/if this happens. A foam pad or roller might give you a better finish, though, if spraying's not an option
