What did i do wrong?

[Trentxxn]

New to tinting. Tinting a 2015 or 2016 ford fiesta hatchback, on the back glass i got these spots that would not stick. Could it be from poor cleaning, or even bad shrinking?  In fl, cleaned with white scrub, gatorblade, black squeegie using j&j and distilled water, maxpro maxjet pro film, and using the dryer sheet shrink method. Squeegying in a star pattern to start and then sideways only after that. Seemed to be only not sticking on the defrosters. Tried heating it out with heat gun, didnt work so i pulled it off

Your pattern may be too big. Did you try wrapping a towel around a hard card to wick away water? While heating outside? Looks like I could've got it to lay down that way.

May have just needed a little more shrink. Try after shrinking lift the film and spray solution underneath the film. Hard card the water out and usually you'll get an extra finger or two. Shrink those out and that'll help out.

That back glass with that much frit around it is notorious for doing that.  Heating it from the inside will not help.  

 

Combine the two other statements.  

Start by raising your dry shrink and spraying water for a wet reshrink. 

 

After install use hard card wrapped in a towel to wick all the solution away.  

 

Make sure not to over shrink before install

Also sometimes you can take a hard card wrap it in a paper towel then shove in there. Apply heat and let it sit.

I let it sit in the sun for a bit then push them down.

Agreed with all the above. Almost had it next time don't give up so quick

I'd agree above. Shrink what I like to do sometimes is after shrinking is wetting under the film glass side and re squeegee just like shrinking and see if any fingers pop up just to make sure the film will lay down.

Idk how those BGs are but sometimes if your film is too long it will catch something and it wont lay down and cause fingers. Look inside and see if your film is touching anything. Also after you are done shrinking, let the glass cool down and then remove your film and spray the BG then put it back as if you were going to shrink it again. Do the H pattern and sometimes there will be some fingers that pop up, shrink those. Remember that the way it lays on the outside is usually the way it is going to lay on the inside.

Thanks for all the help. I tried hitting it with a hard card but it seemed like it just didnt want to lay down. Ill give it another shot soon, thanks guys
