Rattle can it! If you do not like the results then you will not have wasted too much. I painted my XS1B in 1984 using a spray gun that resembled a jam jar and was an accessory for a vacuum cleaner. It used the output air from the cleaner. What a crappy spray gun but I still managed a nice single coat job i.e. no clear coat needed. Now years later after spraying many paint test panels with minimal training I could probably do a damn good rattle can job now.
