Solution to sun rays making my skin darker?
just use car wax/polishing compoundThe wheel should have a clear coat on it.
Although it's considered a little bit shady (and a sign that there might be a meth lab in the house), aluminum foil is the cheapest way to block 100% of the sun's rays, and will leave your room completely darkIt'll work better than anything elseThe foam boards will probably work fine, but it will be difficult to get them to fit perfectly, and light will probably filter in around the edgesKelsey - It should actually make your room much cooler, since the foil will reflect the sunlight back away from your room instead of letting it inOf course, having no fresh air might make it feel a little stuffy.
