Your local automotive paint shop should sell you pre paint wipe. A litre can will cost under a fiver. It is the thing car sprayers use prior to applying paint. Use an old 'T'shirt that has been well washed to wipe over the surface. Do not be tempted by 'J' cloths or similar, what ever you use must be lint free. When painting wear a disposable paper suit you will be amazed at he amount of dust you expel, and wear the hood up. I have used both when painting models and they work for me.
