I have never had the mineral spirits dull the clear. If I have to wipe the paint off I do so and then immediately wash off the mineral spirits using water with a couple drops of Dawn in it followed by an alcohol and water mix. Note

slightly OT) I have found that a mixture of 50% water and 50% rubbing alcohol works well on plastic parts like saddle bags etc; to get rid of static electricity. PPG makes an anti static cleaner but it is pricey and smells just like alcohol. I better knock on wood, but I have cleared over 1 shot using the hardener, allowing the stripes to dry over night and then using the mist method previously mentioned. But that was only because I had no urethane striping enamel. BTW anyone tried the fairly new Dupont urethane striping enamel? I am not real impressed with the HOK or X-otic stuff, probably just me. AL
