wrinkle paint valve cover help

Yes except id only use 320 instead of 100. the scratches would be too aggressive and you could possibley see them after you spray the wrinkle finish. And may take to many coats to cover them up and then it will be a mess. The wrinkle paint does better with thinner coats. When we painted my air cleaner we only used 320 for final sanding and it came out great. Also dont worry if it doesnt look wrinkled right away it takes a while for the wrinkling to appear completely
