Hi all odd question but here goes. I know there are many options in frame restoration powder coating respraying hydro dipping etc etc but these all cost money I don't have. What I do have is lots of patience a keen eye for detail and several rolls of weather proof self adhesive vinyl. If done right would it be possible to recolour a bike frame completely using self adhesive vinyl and a heat gun then cut and apply decals and finish by helicopter taping the entire frame?
Frame coatings serve three purposes:
Corrosion, UV, oxidation, and liquid protection for frame materials that can corrode or oxidize (namely steel) or might get damaged by UV (carbon fiber, wood, polymer, or the glues used in such)
Marketing and looking flash
Stickers, skin, and tape can do a good job of #2 and #3.
They might not do as good a job as powder coating in #1 (oxidation, water) protection especially in wet environments and around areas with complex shapes such as the bottom bracket.
