I am a beginner painter on a budget and I used a single stage Omni paint recently. I wound up with some pretty noticeable tape lines. I tried wetsanding with some 2000 grit but that only dulled the paint, it did remove the paint lines (though not completely). I am not sure what looks worse, the dull areas or the remaining paint lines. Any ideas? I really don't want to paint the whole car over again just because of some tape lines. Input would be appreciated!
