Question 1

Do you apply this immediately before installing the window (I plan on using rope) or can you put it on a while before installing?

Accepted Answer

I'm not certain as to what you mean by the term "rope". I'll speculate that what you're referring to is a Butyl Sealant, what we commonly call Ribbon Sealer.

3M glass products are intended for use as part of the repair process outlined in service manuals provided by automotive manufacturers.  For detailed instructions by car model, refer to information available from the automobile manufacturer.

3MTM Windo-WeldTM Ribbon Sealer is designed and intended for use as a replacement to original equipment butyl installations or as a supplementary sealant when installing stationary glass with urethane adhesive.

3MTM WINDO-WELDTM RIBBON SEALER IS NOT INTENDED FOR A WINDSHIELD OR BACKGLASS WHERE OEM URETHANE WAS ORIGINALLY USED.  For urethane set glass, refer to and follow 3M Auto Glass Replacement Urethane directions.   In some urethane set applications, use of this product may be appropriate as a supplementary sealant.

3MTM Single Step Primer is designed for use with 3MTM Adhesives. It adds strength to the Urethane Adhesive bond, helps protect the adhesive from Ultraviolet degradation, and is used to cover bare metal if damaged during removal.

3MTM Single Step Primer should be applied 10 to 15 minutes before installing the replacement glass.

Question 2

Is there a product that has replaced this primer?  I cant seen to find this product anywhere.  i am using the 3m windo-weld in an upcoming project.
