How to paint with the best results possible?

The original factory cut line is usually pretty straight, but re-cutting your line is a good idea as it gives you a thinner, sharper cut on the tape to avoid bleed under. Use your steel ruler to get a straight edge.

Thanks Tom, i have a steel ruler so i will be doing that, i have noticed that sometimes the factory straight edges are a bit coarse and not always so fine of a cut, so i think cutting a new edge with a sharp blade will help and make it all the better to get good results
