So I lightly sanded back with 800 grit, and sprayed another coat of clear. Unfortunately this last coat has developed a bloom, presumably because it was a rather humid day. Bit of a silly mistake in retrospect, but there you go. I'll let it cure then sand it out. Is there anything else I can do?
I don't use nitro, but it does have some advantages over acrylic lacquer when it comes to repairs, and fixing bloom.
I've copied this from Rothko & Frost website:
"To cure blooming, key the bloomed lacquer to 600 grit, then apply a light coat of lacquer over the top. This will re-dissolve the existing lacquer allowing the moisture to escape. It should now dry to a clear finish. It is important that this process is performed in a dry, room-temperature environment."

That’s good to know, thanks McCreed. I shall wait for a Sydney day with low humidity, which might be a while!
Jonwhitear, I just picked up this thread. I too ended up with a slight orange peel while spraying with nitro (metallic blue), and decided that I didn't want to keep sanding and spraying and sanding and spraying. I finally got a coat that's evenly orange peeled, and decided I rather like it. Sanded the last clear coat lightly, polished with Meguires, and I'm going ahead with it. Don't know whether that is an option for you.
Thanks XP Rider. I'm hoping I'm going to address the orange peel when I get to the final sand / polish. I think/hope I've got a fairly thick layer of clear over the blue. The orange peel wasn't really too bad.
Fortunately, we've had a fairly low humidity day today, and I got a chance to key the bloom and respray. That seems to have done the job nicely, although I ran out of nitro before I had really got enough on the edges.
Did you at least get all the bloom?That seems to have done the job nicely, although I ran out of nitro before I had really got enough on the edges.
