first let me say it good to hear someone wanting to do the job right insted of just cheap!
ok heres how it's done by the pros. takes time and effort but the finish is well worth it!
1. sand down, use a 240 grit to smooth and scratch
2. clean well! use water, white spirit, or m.e.k.
3. tac-cloth wipe over gentley with a tac-cloth
4. spray with a high build primer and leave overnight
5. sand down with 440 grit sandpaper, or scotch pad.
6, clean again!
8. spray paint with the color wanted using smooth even strokes, following contures, and starting the spray before hitting the item.
repeat 4 or 5 times for even finish
9. leave to dry overnight
ok heres where it is up to you, you can laquer or polish! eather way you now have a painted item with a orange peal effect! not good so lets sort that out.
laquer: when dry you will need to sand with 1000 grit sandpaper then spray with a clear laquer and leave to set for 15-20 mins till tacky then repeat, normaily 4 or 5 times,
polish: this one is harder to do but worth it. wait till paint is fully dry, and use wet n dry sandpaper, 1000grit
wet the surface and gentley sand, never let the surface dry while sanding! careful not to remove the paint down to the primer! slow and easy!
once done, wash down with water, then tac-cloth, then polish with t-cut, slow and easy. follow the bottle instrutions.
then poilish with a high shine polish, and buff off. (it's worth while paying for the better quality on this bit!)
repeat for at least 7-9 times and your done! showroom shine! that will last a long time!
i do this for a living!
