I want to eventually place a mirror under my hood to reflect the lights back, currently my hood is painted white with varnish, what would be a better reflecter untill I put a mirror in? Would tinfoil work?
I agree with Riaan. This is your best option.Actually the white paint reflect better than tin foil.
Yes that is true.
Because of the wrinkles in the foil by the time you got it in. It reflect light in every direction. Where the white paint reflect in one direction.
best is Alanod or proper reflectors
