The photo opposite is a good example of what I mean; after respraying parts for my D1 Bantam in my workshop I like to bring them indoors to keep them warm, as it's really not the time of year to be painting parts, is it? However, by keeping the parts warm, just after painting, firstly using a hair-dryer then bringing them into my lounge, where it's nice and warm, I've had no problems with blooming, or whatever you call it.
The latest part to be painted is the lower steering yoke. It seemed a previous owner had done a restoration of sorts, but had sprayed the bike in its assembled state, rather than stripping it down. It's beginning to look good now, though, and I'm looking forward to repainting the tank next!
