Something to do with paint not curing and moisture getting underneath?

And again! Only some tiny spots this time, but why its happening I just have no idea! I'm ready for a rage quit, who wants to buy it off me?? The amount of labour I've stuck into this thing, the starting price is 50k![]()

Could be.. I've spoken to a few experts about it and I might not be letting my first coat dry enough (considering I'm spraying in the evening/night when its a bit colder) so that can often cause that reaction. Or I have moisture coming through my air compressor, even though I have a water trap on it. Hopefully I can figure it out.
EDIT: Came down to the following:
- Spraying in the evenings was a lot colder, needed to wait longer between coats
- First coat too heavy
- Panel needs to be warmed up if spraying in the cold
- Rainy/humid days added a lot more moisture through the compressor so water trap needed regular draining

Righto back on track now. The ragequit is over!
Spoke with a professional who says if the paint blisters like that, you can finely sand it out with 800 grit and then cover it again without needing to reprime. Worked a treat and can finally move on! Might need to colour match this little hotwheels car someone gave me as my next job.

Some minor parts now sprayed like bolts and fuel cap and bonnet arms. Did the underside of the bonnet because I have been spraying all the visible panel surfaces in their correct orientation (ie. standing up or laying down) so after a day of drying I'll be able to lay the bonnet flat to finish sanding and spraying.
Cheers,
Thomas

Sprayed bonnet and boot today. Looks crap. Didn't sand well enough and its so obvious in the finish... Strip back and do it again will definitely have to happen. Bugger!
