Am i mad or stoopid or is this a good idea??? so my clean S3 has been let down by previous owners. the calipers are black with tacky S3 decals but with previous red paint coming through. Due to me being a tightass, and always looking for a cheap option, im considering leaving the calipers on the car and purchasing a portable sandblaster, which i can hook up to my compressor and giving them a quick sandblast so i can paint them black properly. good idea or am i being a div?
