Having just finshed (at last!) a telefonica Suzuki, I can tell you one thing. Of all paints I've used thusfar, the "Telefonica blue" was the hardest by far to "get right". It is a very tricky paint. You have to be carefull not to spray it too thick - ever! In my haste I overdid one layer on the fuel tank... as you say, it's hard work after that.
Unfortunately I know I haven't been much help. I do like the Tamiya sprays a lot, however. Yes, they are expensive, but esp. for these funny colours there's not much that beat them.
I know the guys in the UK also uses Halfords (or something like that) auto laquer paint. Alas, not available in South Africa to my knowledge, so I cannot comment on that. From what I've read, apparently it's very good. Don't know if you've got it in Malaysia (?)
Good luck!
