sanding/polishing linear polyurethane paint?
I just painted above the waterline with Interthane 990 acrylic polyurethane. Some of it came out good and some has orange peel and runs. I'm trying to decide what to do now. People have suggested sanding and repainting but I'm worried that the results will be similar. I'd like to hear from someone who has polished/sanded out imperfections in this type of paint. Is it possible and, if so, what are the steps? Should it be done immediately before the paint is fully cured and hardened or after it cures?
