Are you using a primer before paint? Like Dave mentioned rags that have been washed then fabric softener used creates problems with paint. Liquid softener is the worst.. Even on my towels that I use for buffing and polishing I wash then dry without softener.. I usually use denatured alcohol then let air dry. Next use a propane torch if I have had issues with fish eyeing previously on the part. Helps pull the oils and impurities out then Ill use a different rag with alcohol and air dry again. Lastly I apply a light coat (tack coat) on the part let sit for 2 or so minutes then start applying full coats.. Hopefully this helps.
