i want to tint the front windows on my 99 sport. i was thinking of doing 5% which is limo tint. all my rear windows have the factory tint and i think it will look stupid to have 5% on the front doors and then whatever the factory is on the back. can i tint over the rear windows that already have tint? if so what % should i do on the rear that will get me somewhat close to the 5% on the front? im getting the tint off ebay: http://cgi.ebay.com/ebaymotors/ws/e...30275974574&ssPageName=ADME:X:RTQ:MOTORS:1123 it comes in 50, 35, 20, and 5% any recommendations?
