How to prep rear glass properly?

[Darius]

Hi, how to prep rear glass properly for tinting? I use water based glass cleaner and white brite pads, but I can't rid of all contamination, maybe I need to try carefully scrape between defroster lines? I always scrape side windows and they looks good, and on back window there is not so much contamination left but I'm not satisfied enough, thanks for any help.

Are you the one applying the tint?

[Darius]

Yes, I have tinted only 4 cars, I just wached tutorials on YouTube and tryed to do, I do heat shrinking and always use reverse roll technique for rear glass, I'll try to add some photos.

There's so many number of things it could be. To answer the one question though, no you do not need to scrape between each defroster line.

Thank you, and if it only trapped small air bubbles maybe there is a possibility to fix it? Or better to avoid it? Maybe I have not enough skills to use squeegee, for training purposes I use "Lexen professional tint film" on ebay it cost 150 $ for 40" x 200 ft (It looks to cheap to be professionall) I have no idea how to add photo

If it says file to big you can download a photo resize app and go from there.

I think the main problem is being that you have only tinted 4 cars and your experience level hasn't even broke "0" Those youtube videos will give you somewhat of a guideline, but definitely not going to turn you into a pro overnight. Just my 2 pennies.

I definitely agree with you Ocala, but I want improve myself, I do not expect that someone will write something ant it will solve all my problems I just want to do better job every time I tinting, but is very difficult then I don't know reasons and solutions of my fails

I hope you can see it, it's difficult to take a photo, it looks like empty air bubbles, here I used baby shampoo with water, second my job was done with waterbased glass cleaner and it was 80% less bubbles, center of glass always clear, bubbles are more noticeable in sides of rear glass

and this is my las job
