I applied the first coat of Spray Max 2k High Gloss Clearcoat aerosol and the finish was perfect. I sprayed the second coat of Spray Max 2k High Gloss Clearcoat about 7 hours later and when the can got near empty the finish went very dull. (Almost like real light orange peel. Do I now need to sand everything back down and re-paint or can I just spray on another coat of the Spray Max?

Thanks
