I've used the plasti-kote top-coat, and it's really thick. Comes out of the nozzle poorly, and has very average coverage. $18 a can from Bunnings. I'm yet to try their primer, but it is enamel-based...
Rustoleum Spray-all is quite good. I'm using it as a primer, has good coverage, sticks well with a light sand, fairly hard to get runs, and using the supplied tip, you can spray upside-down (the can, not your body!!) It does show-up any imperfections in the sanding though. It is also enamel-based. About $16 from Bunnings.
Rustoleum Sandable Primer is also very good. Same again, I'm using it as a primer, but am using custom grafitti caps, as the factory cap has quite high pressure, and a large fan. Also requires a light sand, but also works as a mild spray-putty. I have had one instance where the paint didn't stick to the blaster in a couple spots, but I think this was due to insufficient cleaning of the blaster after prepping - yes, I am a little impatient. It's also enamel-based, but is only $4.50 a can from Mitre 10.
Tamiya Spray Primer is probably the best that I've used so far. Really good nozzle, fantastic misty spray, covers well. Also requires a light sand, but is acrylic-based, and is ideal if you're using Ironlak or Kolor as your top-coat. Only down-side is I'm paying $18 for a very small can (enough for 1 Longshot, and half a Maverick, even used very sparingly. No problems with spraying enamel top-coats.
IronLak and Kolor Acrylic top-coats are very impressive. Comes with 2 different caps, very vibrant colours, and a large range also. Acrylic-based, so you need to match it up with an Acrylic primer. Good coverage, sticks well. Stays sticky for about a week, even through the clear-coat. I'd suggest an extended curing time, and it should be fine. $6.50 a can from ozgraffiti or the Butcher Shop WA. Postage is an absolute killer though.
White Knights enamel sprays come in a multitude of colours, including some nice metallic's. Good coverage, average pressure, fairly simple to use. I've heard the same brand primer is also quite good, but I've been unable to locate any to trial. $7.50 from Mitre 10 per can.
Export Paint enamel sprays are also quite good - I've had no issues with this brand so far, and I've used it as top-coat on 6 blaster's so far. The pressure can be a little high at times, and the caps aren't all that great. I use an adapter to change the can from male to female cap, and use an adjustable pressure cap, and that works well. Also, I leave them in the fridge for a few hours, which lowers the pressure to a decent output. $2.50 from most discount stores per can.
Septone Spray Primer/Filler is also not a bad prep spray. It can be a little thick, and does generally need a light sand between coats. Does fill minor sanding imperfections, which is quite handy. Even though it is enamel-based, I've had issues using enamel top-coats with it (ie: orange peel and spider-web cracking). Works well with Acrylic top-coats. $17 per can from Mitre 10, and is double the size of a normal paint aerosol. EDIT - I've just completed testing of this primer with enamel paint. If you give it 48 hrs to cure, you can successfully use enamel top-coat without any bonding issues.
That's all I have thus far. I'll update if I find anything new - or if I can ever get my hands on some Krylon Fusion (without the 8 week wait to import it into the country!!)
