Geoff, my 3-wheeler had goose pimples all over it and I was sure that a bare surface respray was pending. Because I had nothing to loose I polished it with an abrasive (T-Cut in UK?). It took a lot of ellbow grease and a cheap polishing machine but at last the pimples were gone and the paint (or some of it) was still there and shines nicely - £££ saved.
Give it a try. If it goes wrong, what have you lost - it was due for a respray anyway.
