This is pretty much the only answer I’ve found. Bit of a faff.hmm yeah never easy on those wheel nut area etc
small gun on pencil jet setting , shield other areas with a bit of card etc
With the fan right right down I'd just pull the trigger to get a slight paint flow until you can just see you've enough flat looking paint on ie not dry coverage, I suppose each situation is differentI've tried everything. The wheel nut recesses I would brush in afterwards and that's grand but other deep concave parts are a pain when on show. I was hoping to have someone say 1/4 fan, half fluid, longer distance, 10psi, 27' angle etc. I've tried so many ways over the years and I'm not alone I'm sure.
