Get enough paint to make sure you can re spray a panel of needed so the color match is perfect (some shops can remix perfect. Some can't) if you go with any metallic or pearl spray it on top of the base in an inner coat clear. And give yourself plenty of clear to wet sand with. Also if your doing this at home make sure you clean your garage better than "I think this is good". (learned that the hard way). Also not a bad idea to wet the floor if you can so your not blowing any dust up.
Good tips ^. Without a pro booth yer chances for perfection are slim,I have done it,but I'm lucky,not good.
One drag of that hose across a dusty floor...yuk. There are a thousand tips the first time painter could use,we could be here for a week.
Cleanliness is everything. A spot away from the project to mix the paint(get out of the fumes). Ventilate as best you can. Keep an even room temp(whatever the manufaturer suggests). Hang the parts with weights on the bottom,or hold them(in a non-painted area),light plastic parts will move and spin when the gun pressure hits them.Set yer PSI at the gun(with trigger pulled),not at the compressor,PSI is lost in the hose etc,plus you dont want to walk back and forth. Hopefully yer compressor is large enough to paint with,you need to check if it can handle painting,its called CMF. Move yer body,not yer hand for big parts. Use a motion like yer standing at a sliding glass door and yer body is motionless while just yer arm moves for smaller parts. "Fanning" the object to be painted wastes product and builds to high in the center,to thin on the outsides.Take yer hand and pretend yer spraying something (bug spray,room freshener) at yer monitor.See how yer hand is close in the middle of yer swipe,farther away at the ends.Thats bad. Use a large enough enviroment so you wont be bumping into parts when you turn/back-up,its easy to get dis-oriented after you've been in "the fog" for awhile. Dont pull/release the guns trigger over a part. Start the spray before it hits the part,continue to hold until after you have passed the part.(no dribbles,sputtering gun,no surprises,no thick/thin spots). I like to paint the edges first and hit them twice as much as the rest of the peice. (If you wet sand,the edges will be the first place to get "sanded thru".) Lots of light in yer booth is needed,even light. A 60 watt light bulb in yer basement aint gonna cut it for this operation.
Bored to fuggin' tears yet....
I'll stop now. It ain't rocket science,but its no walk in the park either. Painting is fun. Sitting back and admiring the job I did is a huge reward for me.
I love the mechanical side to bike mods,but its like giant Lego to me,you have to put the peices together,most folks can do a decent job of it.
Where as painting...thats artistry. A wicked paintjob gets noticed bigtime. Those parts you custom built will get noticed too,put a cool ass paintjob hits you in the face.
Good luck,
RSD.
