I know I'm doing a JM on it by responding to me own post, but having read the thread fully, a few pointers are warranted.
Tamiya paint has an exceptionally high alcohol content, and if not dry) plasticised) will peel like sunburn skin when the tape comes off.
Two ways to absolutely prevent this. Wash the model in fairy liquid etc. Greasy models are a no-go. Even a thin coat of primer is preferred to a factory surface. Key with 0000 wire wool if primers not available.
Halfords stuff is appalling. One minute it's misty snow, the next snotty ice cream. Hmg produce a primer for brass, sold by Cork outfit mithril.ie that is exceptional and they provided me with technical specs to back it up.
For more standard work, army painter make coloured primers, but their white is a thing of beauty. Sets in about 5 minutes and available from the gaming lads on jervis St in Dublin.
If you want to prime white, mask the stripes, and do orange and black later (best method), there is no better alternative IMHO.
Cheap compressors from Taiwan are as good as expensive ones. The pulsing myth is just that. When it begins to fail, after about 300 hours, the internal rubber seals loose integrity, and its just a paper weight. Or something you donate to the MRSI...
There are several low tack tapes available from builders providers etc. After years of use, green frog tape is excellent for large area coverage.
All of the above is said only to prevent "the expansion of your vocabulary" as Tony Wright would opine.
They are merely tips based on the inordinate amount of mistakes I've made, in the interest that any other punter may avoid. I'm not Martyn Welch or Tim Shackleton, nor claim to be. I'm sure others have their "go to" methods.
Looking forward to you getting stuck into washes and powders next noel.
