I've done some research into paint systems and decided to go with quality aerosols, rather than buying all the spray equipment (although I do already have a couple of compressors) or, heaven forbid, paying someone to do it.
You can split the painting process into three layers. Filler and primer, which will effect how smooth it is, the colour layer, and finally the clear coat, which effects petrol, scratch and chip resistance.
This lot - some sanding paper, a sanding block, some disposable gloves, filler, etching primer (to grip to the metal), high build primer, a tin of candy blue paint, and a tin of clear coat - was £62. That should be enough to do a smallish tank and one mudguard, so it's not cheap. But there's nothing worse than a paint job that looks cheap and has big petrol runs from where you've inevitably spilt some filling up. I got all this from KGC in Bristol, who were friendly and helpful, even though I went in when they were trying to get their deliveries out not even knowing what colour I wanted. You can find them at www.kgcbristol.co.uk. I'm going to lay this lot down then finish with some white pinstriping - Nice!
