Heyy i bought these cheap window visor with only 3M double sided tape.
My dad told me he had those with only tape and they fell off when he was drivin on highway. That got me so paranoid.

So could anyone write me a diy on how to make those pin?

 

I have had them on my Caravan for 6 years and on the Fit for over a year and they have not blown off or ripped off in car wash.

The ones on the the Fit are the cheapos. Just make sure to clean surface well before installing.

 

I have a van and pickup that have had the stick ons for 10 and 12 years... The ones on my Fit a couple of years with no problems in many miles of going very fast and a lot more no so fast.
