Homemade Paint Booth
Lighting is also a key factor - my shop has the standard flourcent bulbs - but the more the better to be able to see what you are doing. That is a very key factor - also the more box fans the better - I did one at first then went to four churning that worked the best. With a little ingenuity you can also build a 2x4 frame and coat it in plastic outside - you can even make it a portable paint booth.
Another story of mine is afte sanding, priming, filling my Barracuda for the first paint job after hours and hours and hours of work - I got a $50 Chevy Cavalier with the typical white paint that flaked off to the bare primer... the motor was great the interior was great the only problem was the body - since I didnt care too much for it - it was just a beater.. I gave myself the chalenge - could I paint the car in 12 hours and have it look as good as a month of prep time. I also wanted to see if I could just shoot it outside with no protection... I went to the local paint shop got a gallon of what was supposed to be Corvette Yellow but had been mixed improperly - it was brighter than yellow! for about $50 as a reject and shot it that afternoon - I block sanded really quickly all of the flaking paint shot a coat of primer etcher, then sealer, then the final coat - the sad part was I had just as good of a paint job as the months I had spent on the cuda...there were no dust spots and no bugs in the paint either... still i think I was just lucky - dont recomend doing that all the time though...
