Thanks guys, I will go with that then, a FP it is!
Yes Bdgr I know what you mean, I spent quite a while sanding the very slight seam line out and tidying the edges. My brother is a great sprayer and complained at my terrible preparation work
He made a really good job, the finish is like glass and it shines lovely

I think the only way you will get a good spray finish is by using a good spraying compressor. Rattle cans would never get it to look so good imo , the dreaded "orange peel" is the main problem.
