You do realise if u put a 30% tint on the front it's gonna be illegal
Most front windows come with a factory tint usually 10-15% I found this out after driving round for 2 yrs with limo black all round b4 i got stopped & made to rip it off at the road side. I did count myself lucky as he didn't give me a ticket & he showed me the factory tint was 15% on the astra with his little photometer so putting any tint on the front is risky, won't stop me tinting the Veccy though. Limo black on the back & a light smoke on the front is ;-)
btw. Has anyone any tips for application to rear window in a saloon? The only 1 i have probs with hatchbacks & estates are much easier
