Was the paint from can or actually done by gun? the problem could of beeen that you didnt let the paint flash off long enough between each coat, if that was the case the solvent in the paint was trying to escape through the next coat and that can cause bubbles.
also could have been an oily surface, a good product to use before spraying is called 'prepsol' but it may be called something different other there?
whats with all the negativity, i believe anything can be done, it just comes down to the issue of money, in this case a RB20de ALOT of money would be needed! and aquiring a engineers certificate would be hard.
has anyone ever thought of putting a mitsy RWD engine into their datto? i recently brought a 1979 lancer coupe with a 1600 *not the stock engine* in it and its actually pretty strong and has quite a bit of grunt, also its not that much larger than a a14/15. So if anyone wants to look into it, i think the engine code is 'G32B'.

oh another thing i forgot to mention, it is a OHC engine and comes in both turbo and carby options.
