Here we go i found it..
From SH81..
'you need to make sure you rub the deck down really well with wet and dry paper to get it smooth and get rid of the original coating. Get rid of any dust or loose dirt then spray it with primer which gives a base for the paint to take to. You then do a few coats of paint, you can use wet and dry paper again to flat out any 'orange peel' effect- Be careful here though, make sure you use a fine grit- about 1500 otherwise it'll scratch or go through the paint. Then laquer it with a clear aerosol lacquer, I used quite a few coats to stop the paint chipping easily. Once thats dry just polish up to a shine with a soft cloth and car polish. Its a bit of a ball ache but worth the effort if you want a good finish.'
