G'day, Patrick.
This model is coming together nicely, mate. I also like the colours you used for the wing, would you mind telling us which colours you used? But I really like your cockpit. You've done the rigging very well and I like the colours you used.
As for the spots, this has happened to me when using Future/One Go/ Kleer on humid days (and sometimes with Humbrol Matt varnish as well). With Future, another light coat over the spots can make them disappear (it also works if decal setting solution has made the Future go cloudy). Or you could incorporate the spots into weathering, if you are going to weather the model?
You're doing well, Patrick.
Dal.
