Tip of the Week VOTE

i just did another A5... this time i popped up the rear deck to see what we are up against...i covered the amp with a towel and plastic and on top of that i put tissue paper on top of the plastic to see if it gets wet... under the rear deck they have a inverted sub woofer and tweeters...so i removed the sub and tweets and went on with the install of the tint ...i soaked the hell out of the rear glass 2 times trying to get the amp wet but no such luck the water does not go down to it not even one drip on the tissue paper ...so in my conclusion the inverted sub has to soak up the water or it goes into the voice coil because it is facing upward and it has to short out the amp ....water never even came close to being near the amp or its wires in the elevated area in the back left rear corner where it is mounted....so i am going to protect the woofer and tweets on these cars in the future.... hope i was able to help you thanks big joe class on glass ps to replace the amp with labor is $1700.00 at audi and they have a bulliten posted about window tinting on that car the car has no warranty on the amp if it was tinted !!!!

So I've been doing some thinking and playing with some stuff. I recently tried a water based solution using a mixture of Dawn dish soap and white vinegar to use as a window prep cleaner (similar to the way one would use Dirt-Off). I've had some decent success using this mixture, getting a much clearer finished product after the film is installed. I spray the window, scrape with a razor blade, then respray (light mist) and scrub the window with a white scrubbie. Then I squeegee this solution off and mist the window again with my slip and give it a final squeegee to ensure all of the dawn and vinegar is gone. This seems to really cut through the grime and film on the window before installation.

Here's the reasoning: Dawn is a degreaser, and the vinegar has acidic properties to help cut anything the dawn doesn't get. Yes, it doesn't smell pleasant during the process, but has given me much clearer tint.

The last batch I mixed I used ammonia instead of the vinegar. I noticed the blade doesn't move across the glass as smoothly as with the vinegar. But it still cleans well. And yes, I do use caution using this method, and check for scratches. Also added some baby shampoo for a little more slip. it helped.

Anyways, just sharing with you guys. Yes, I'm still a noobie tinter, and trying out different things. Any thoughts or see any issues with this process? Probably seems like a lot of work when I could just buy a bottle of Dirt-Off and be done with it, huh?

hey i wonder if i got Jeff Rutherfords vote
