What are the chances of me being able to spray in the affected area so that you wouldn't notice?
Obviously I would have to laquer it after too.
If the base colour is a good match, even with p-can base coat can be applied OK, just go gentle, not too heavy (or the metallic particle will sink) and blend it in - cover the effected area and beld in higher, do not try and base coat the whole panel.
Your laquar should cover the whole panel once the thinners in the base coat have flashed off (gone matt), tack cloth or else you may get 'moon dust' and laquar peel.
I have a compressor, but I have no where to spray 2 pack safely unfortunately.
2-pack is excellent, I paint with this even now, yes its toxic, use a good mask that filters fumes as well as dust (you should go further, your risk as is mine), paint in a garage or open area illegally but make sure no one elses cars are anywhere nearby as the overspray will stick, and cover your whole car so it doesn't stick to any unmasked panels.
If the finish isn't great (be careful not to get runs) just rub down with 2000 or 2500 grit and compound/buff with G3 paste, its what the bodyshops do if they turn out a bad one.
