Homemade Paint Booth

dude you can go as big or as small as you want, i had a binks spray booth when i did it for a job and yah it was nice, but now for a hobby i have a 30 by 30 shop with a 18 inch squirle cage fan vented into the roof(which you shouldent do if you are doing too many projects), i open the window a bit and the air is just fine. wet the floor, wipe the walls and the roof (the last thing you want is little dust particals falling when you dont want them to). ive done probably 20 vehicals in there and never had a problem. the only problem with washing the floor is be carefull with your hose not to drip water on the new paint, another trick is groung your metal to the floor, i know it sounds silly but it dose stop electrolisis and or static electricity which causes alot of dust. bugs well unless you are in a high cost spray booth you are suseptible to bugs, just leave them be untill the paint gets tacky, take a pair of tweesers and if need be take a piece of masking tape and roll it loose so both sides are sticky and carefully remove anything that is left. if you are using base clear it is verry forgiving, if your dust or bugs are in the base take care of them then before you clear, if its in the clear, same thing but you can also have a couple of small marks in them, burry them with clear and polish them out. hope this helps out
