If anybody has any tips on getting spray paint to have crisp line I would greatly appreciate it. I have been 3D printing a suit of armor from Halo:Reach and I cant get clean lines when using painters tape and the spray paint. I have tried Scotch Blue with Edge Guard and Frog tape but I couldn't get smooth lines with either. I only chose spray paint over hand painting due to the ability to not have brush strokes on the large faces of the armor and paint matching the spray to an acrylic may be a challenge to do any touch up. Again any tips would be greatly appreciated.
