billy sugger Posted May 28, 2023 Share Posted May 28, 2023 Wet and dry emery cloth, 1800 grit or finer, rub down very gently after each coat. This removes any potential lumps left behind by aerosol cans Quote Link to comment Share on other sites More sharing options...
Angela Collen Posted May 28, 2023 Author Share Posted May 28, 2023 Thank you Billy, got all I need now, on my cb400nc superdream 1983 they put a black plastic front mudguard, not chrome,previous owner made bad job of covering chips, can I wet and dry sand over paint on plastic? and did I see there's a different primer for plastic?

billy sugger Posted May 28, 2023 Share Posted May 28, 2023 You can, but get some adhesion promoter before starting any spraying, and yes there is special primer for plastics/pvcs. Rub down the mudguard to remove all blemishes then treat with adhesion promoter before applying the primer, allow to dry then prime, then gently rub down between each coat, using 2 or 3 coats Quote Link to comment Share on other sites More sharing options...
