SAND PANELS TO BE PAINTED WITH 400GRIT 3m WETSANDING PAPER FOLLOWED BY 600GRIT3m WET SANDIND PAPER. IF ANY INPERFECTIONS FILL WITH STANDOX PUTTY OR 3M GLAZING PUTTY. SAND PUTTY WITH 600 GRIT WET PAPER. CLEAN PANELS WITH DUPONT 3900 0R ENAMEL REDUCER. MAKE SURE THERE DRY AND PRIME WITH DUPONT 4004 ULTRA PRODUCTIVE PRIMER AND USE A GRAVITY FEED SPRAY GUN FOR BEST RESULTS.APPLY 3 WET/MED COATS.LET DRY FOR 2 HRS. RESAND ALL PRIMER SMOOTH WITH 400 3m PAPER AND THEN 600 3m PAPER. DECIDE ON COLOR AND YOUR READY TO SPRAY BASECOAT.

No he's a chemist that specifies different coatings for different materials, I can put you in touch with a good decorator though if you'd prefer Wink

Regarding your old paint reacting with the new, you can buy an isolator paint which you spray over the old before applying the new paint. It forms a barrier between the two and stops any potential reactions happening. Obviously do any repairs and preparation, flatting off etc, first before applying. You can buy some called 'Barcoat'. Just ebayed a 1ltr tin, going for £13-15. Hope this helps.

forget the 600 grit you need to get all that crap off your pannels try 120 grit use a machene on larger areas if u can get ya hands on 1  b careful not to dig the edge in try to keepit flat      once u got it stripped go over it with a bit finer paper about 320 grit  then apply 3 good coats of primer  make sure u get a primer suited plastic/fiberglass r not the same      when the primers dried then get the 600 out and wet flat this will take out any sanding marks showin through the primer then apply your colour again 3 coats then dependin on how fussy you are u can wet flat with about800 grit and stick a couple more coats on or wet flat with 1200 grit or higher and polish    i bin a paint sprayer for 26 years it realy aint  technical stuff good luck with it
