After several coats of Target USL and TransTint as tones without problems started topcoating with clear USL and up pops fish eyes! Received a shipment of Fuhr #330 Universal Cleaner that was used followed by white vinegar/water to neutralize the cleaner then 1:1 acetone/water to rinse out gun between coatings. Sanded down today leaving pinpoint spots of shiny finish and sprayed clear USL and they returned. Wasn't surprised but would like to know what the cause is to avoid replication! Soaked and brushed gun components prior to spraying today but didn't use vinegar as that is MY primary suspect (from my point of ignorance as chem lectures weren't meaningful and they were YRARS ago). Ideas?
