The Stovebolt Site Forums The Shop Area Interiors Window installation Tape--Need advice on using

I am getting ready to install new side glass in my 49 GMC and have already painted the window frames. My old regulators were shot, so splurged and put in new regulators. Lookiing for advice on use of window setting tape acquired from American Classic. My old original type manual tells me to put the tape in place using 10 w oil which will help swell up the tape after the window glass is installed. The oil is supposed to swell the tape to help with final setting. The particular tape that I received has no adhesive, but has a cloth type backing with rubber on the opposite side. I am assuming that the rubber side would contact the glass with the cloth side contacting the window frame. Looks like there will quite a bit of excess tape after setting the glass, so planned to cut off the excess with a sharp utility knife. Also any good photos or diagrams of the installed window regulators would be great. When I got the truck, all of the internal door parts had been removed so I didi not have any reference for reinstalling. My manual shows setting the regulators into the lower door opening to start installation, but that is about it. I have the regulators bolted into place and want to make sure they are installed correctly. The regulators do crank up and down well as long as I keep the support arms from flopping down and catching on the supports, etc. Any advice on both topics would be appreciated.

Willie,
My 4t6 is different but installation should be similiar. I bought tape from local glass company and was all rubber and three times wider than needed. I used liquid soap to ease installation. I taped setting tape to glass, wetted with soap and tapped into channel. Then the tape was laid into bottom channel and attached to upper frame. Excess tape was cut with utility knife. I installed into door with new whiskers and channel felt and clamped into place to "set" new weatherstripping. I installed newly painted and greased regulators and it seems to work with ease. It hasn't been road tested or leak tested as it still in garage. I also insulated with a product called "Reflectex" bought at the box store. Some pictures start here. Hope this helps. Have fun and good luck

Great pictures and advice. My 49 GMC doors only have access holes so installation of everything is through the holes. Looks like your doors would be a lot easier to work on. I called Classic Parts for info on the window tape they supply. Apparently you soak the cut to length tape in 30w oil for about five minutes before installing. The oil helps with sliding the glass into the channels and eventually swells the tape for a tight fit. Some people apparently use weatherstrip adhesive, but that makes for a challenge if you ever have to replace since you have to clean out all of the old adhesive. After installing and letting the oil sell the tape, you trim the excess with a sharp utility knife. The above directions using oil were the same technique used in the old shop manual. I do know that oil can be hard on some seals, so was surprised to hear that the oil technique was used on this product.Thanks

I used a heat gun to soften the new tape. I also used a litle WD40. And of course, trimmed off the excess when done. I did all the work on a soft blanket, on the floor. I used a soft blow mallet to work the frame onto the glass. Worked out great... didn't know about the oil trick.. makes sense though.
