## Description

Securely Set Windshields in Place: 3M Windo-Weld Super-Fast Urethane delivers a secure and permanent attachment of the replacement windshield.

When properly applied, our adhesive prevents annoying leaks where rain and water can seep into the vehicle between the windshield and auto body. Your Choice: Manual or Power Caulking Guns: 3M adhesive may be applied with either a manual or powered caulking gun.3M offers manual applicator guns with an 18:1 ratio, including the 3M Professional Caulking Gun - part number 08993. Electric, battery or air-operated caulking guns may also be used. Adhesive offers a 10 to 20 minute work time. Other Applications: Besides replacement auto glass installations, this adhesive may also be suitable for some non-structural body panel applications.

Review: Perfect application for BMW convertible fabric window installation - I’m updating after 4 years now. I Used on a separated rear BMW convertible glass. The bond is still holding up great and still shows no signs of separation. Have a helper, she can help keep clean - * below you will read Does what it’s supposed to do. I Used it to install a rear window on a BMW convertible. It worked great! * buy the window suction clamps 1) Use the 3M primer with this - **it provides the bond to glass- I also placed some on the fabric, I don’t think it would hurt - the weld won’t bond to glass without 2) Use small bead (not heavy) all around the edge of glass - ** make sure it’s enough but not a big glob - 3) tighten window suction enough to start the squish of weld. **Do not extremely over tighten. That will squeeze to much weld out and window will not stay bonded. Let set for a hour 4) Use plastic/ rubber mechanics gloves and finger a clean bond around window. Just like you would with window caulking. Be careful on touching anything with the weld. It will be very hard to remove. Thinking clean will give you a nice result - I had a helper (wife) take a old towel to clean excess weld from my gloved finger so I could continue the clean caulking edge I was after. When the job sat for 26 hours the weld was super hard and looked great around the glass edge to the fabric. * keep in mind this weld is a glue - if it gets on anything- it is on it. You can scrape it off glass with a razor but avoid painted or fabric where you don’t want it as it will be hard to remove. Take your time and you will get the bond your looking for. This saved me thousands of dollars vs a replacement of top that I was quoted as the only way of fixing Other items I used to install a rear glass on 135i BMW convertible. * C.R.

Review: Mustang convertible rear glass repair AAA+++ - I was extremely happy with how this adhesive worked ... I followed directions found on the internet using suction cups, 3M primer, primer spreader sticks/balls and 3M Window-Weld urethane adhesive w/wood strips to spread the load. I was particularly pleased with the good initial tack and the extended open time of the adhesive. This allowed me to move the glass and stretch the top while my son perfectly aligned the fabric to the existing glue line resulting in a very near perfect repair. The rear glass bond had failed very quickly (over 2-3 days) resulting in over 3/4 of the glass coming loose. First the top section separated and by the time my supplies arrived the passenger side had separated past the corner and half way across on the bottom. It took 3 separate "gluing" sessions to bond it all back up over a 2 day period. The first 2 sessions re-glued the bottom section and the upper corners leaving the full width of the top glue-line for the final session. BTW - The picture of the passenger side of the glass is the trial-fit and does not show the use of continuous spreader-sticks around the corner. I don't think the "After" picture shows it but there is a small flaw in the bead across the top ... I had too much space between the clamps and I did not get perfectly consistent squeeze-out in one small section. The important note is that by saving the "tip" from the glue cartridge I was able to plug-it-up and keep the adhesive from drying out so I could continue to use it as each section cured (4-5 hr minimum). In hindsight, I should have done the final top section in 2 parts but I was (incorrectly) concerned that the adhesive would dry out in the tube before I could get the full window re-glued. Excess primer drips/runs and Window-Weld adhesive squeeze-out was of no concern. A razor knife cleaned it all up both perfectly and quickly. It has been a week since the repair and there is no evidence of the adhesive failure ... I expect it to last longer than the rest of the original 13 year old top. If the last of the original/factory installed bond fails I will not hesitate to order again and repair it in exactly the same way. Totally satisfied.

## Questions & Answers

**Q: So do you have to be dead on perfect the moment you set the glass, or can minute adjustments be made once it's down?**
A: It takes 48 hours to cure. You have 5 to 10 min before you can't adjust window anymore.  Side note. Urathan will stain anything it touches even your skin. So be very careful and don't use more than you need to.

**Q: Does it come with a nozzle?**
A: Mine did come with a nozzle

**Q: What durometer does this stuff cure to?**
A: Hi Travis! Thank you for your question. The 3M 08609 Window-Weld Super Fast Urethane has a 55-60 Hardness (Shore A).

**Q: Will 3m 08693 auto glass urethane secure the rear glass to a canvas convertible top? sides and bottom have separated and need to be glued.**
A: Yes. I purchased a small piece of convertible roof fabric on ebay which matched my convertible's black top and I cut it to fit the lower part below therear window with about a one inch overlap onto the window. I followed the adhesive directions and glued the new material right onto the window andthe old convertible fabric. I let it sit for 48 hours. Today, you can hardly notice it was repaired and the adhesive still adheres to the glass.
