I need a visor for my helmet but I'm having trouble deciding how to do it. I can't do vacuum forming since I don't have a chrome paint and I'm not sure where to buy colored mirror tint's in small quantities. Any help?
SpazStix makes a chrome spray paint that can be used on the interior of your visor. While it does not go on as smooth as an airbrush paint and as such has less clear visibility, it is available on Amazon and does not require additional equipment like an airbrush or compressor.
For small amounts of mirror tint, search for "Flexible Visor Material" on Etsy.
This might sound obvious but... "Then buy some chrome paint".
I mean... If that's all that holding you back then why is it an issue? You're going to be spending a lot on your overall armor between materials, fabrics, strapping, tools & consumables and paint.
