If you gonna go ahead with spraying in in your garage, spend the better part of a whole day cleaning, hosing, and blowing out the whole area with compressed air, roof, floor, everywhere. Make sure the car has been washed after you rub your primer back, fit a moisture trap to the air line, and one at the gun. Gun setup around 1.4mm. Do not rush anything just to get the colour on, buy some tack rags and paint strainers from a paint supply shop, use as low as pressure as you can. I noticed your primer has gone on a bit dry (can see stripes..) need to get your technique going a bit before you apply your colour. Buy a 2k mixing stick with the correct ratio on it. And practice a bit first, you need to spray it on wet, but not to wet. 2k iff sprayed to light will look rubbish, and too heavy will be full of runs. Figure out how your gonna attack it before you start, when you go around the car finish in a spot thats not very noticable.

Oh and personally think bonnet needs more work, them black stripes are gonna show up in finished product. and buy a buff! will need it. Good luck dude, practise 1st on some old panels!
