"I feel a draft." Girls hate it when a blast of cold air and rain conspire to flatten their 'dos. Combine that with the lack of aesthetic charms presented by our '86 Chevrolet Caprice, and it looks like we're never going to get a girl to ride in it. It needs all the help we can give it. Fixing the weatherstripping is a good place to start.

Unlike for our '91 Firebird, which also repels women like dog breath, finding new parts is no picnic. It's a mid-'80s, fullsize coupe with a very small following apart from Midwestern geriatrics who have relocated to Florida, the lowrider and donk crowd, and nostalgic cops. Square Caprices are a dime-a-dozen here in the junkyards, but 99 percent of them are sedans. And though many sedan parts will work on the coupe (headliner, carpet, and more trim and molding pieces than you'd think), those parts have long been rendered unusable because of years of fleet service. So rather than packing the void in the door seals with strips of foam rubber, we performed a lengthy search on the Internet that turned up some options.

The door weatherstripping was not much of a problem. SoffSeal sells a kit for the coupe, so a call was made, and the box arrived within a week. The door-seal strips and window channel posed more of a problem. GM discontinued them, and any N.O.S. stuff that had been sitting on a dealership's back shelf cost too much. Eventually, J.C. Whitney came to the rescue for half the price.

We were a little freaked when the boxes were delivered. J.C. Whitney actually does sell replacement body parts, trim pieces, and mechanical items, some of which are custom-fit. You never know what you're going to get from the universal parts bin, but we were pleasantly surprised when the window channel and door seals turned out to be high-quality pieces. The rubber was good, the felts were soft and flexible, and the pieces fit the car perfectly.

So, while it may be dubious for a Caprice of any vintage to grace the pages of Car Craft, the process of replacing its weatherstripping with a generic brand is applicable to a variety of popular cars. Follow along as the Caprice gets its door seals tuned up.

    Door Weatherstripping
    Removing the door weatherstripping requires the use of a good adhesive remover. On this car, the bottom half of the weatherstripping is held in place by plastic push clips, but the remaining areas around the window frame and down the front of the door to just below the hinges are glued on. We soaked them in 3M Adhesive Cleaner that we purchased from a local body-shop supply company.

    Scrubbing with wire- and nylon-bristled parts-cleaning brushes worked far better than hacking away with putty knives and screwdrivers to remove the remaining weatherstripping and adhesive residue.

    We test-fit the new pieces first to ensure proper alignment. Start at a corner, since it's the most obvious reference point. A plastic Bondo spreader helps tuck the weatherstripping into its channel. Once proper fitment is confirmed, push the clips into the door.

    To attach the weatherstripping to the window frame, apply a bead of adhesive, also available from a body-shop supply company, and push the strip back into its channel. Wrap a couple of pieces of masking tape around the window frame to hold everything in place until the adhesive dries.

    Door-Seal Strips
    Drive with your arm out the window much? The door-seal strips (also referred to as door-belt weatherstripping) have not led easy lives, either. In addition to preventing window rattles, these strips keep water from flooding the doors and ultimately rotting them from the inside out-something these cars are notorious for.

    The seal strips are held in place with Phillips-head screws, some of which are blocked by the glass, even with the window lowered all the way. Since the window-channel weatherstripping is also going to be replaced, we decided to remove the glass. The glass in this car is bolted to the sash rather than bonded to it, so removing it is relatively easy. Loosen the glass-to-sash bolts, and lower the window all the way.

    The glass can be lifted out of the sash with the bolts loosened. However, if you choose to remove the bolts completely, be sure to support the bottom of the glass or it will fall to the bottom of the door. Once the glass is free from the sash, tilt it forward to pop the retainer out of the window channel and lift it out of the door.

    Installation is just as easy. Drop the seals into place, and, if necessary, align the holes in the seal strip to the holes in the door with a pick or small screwdriver, and reinstall the attaching screws.

    Window-Channel Weatherstripping
    The Caprice's window-channel weatherstripping was also fragged. It fits in a metal channel in the doorframe and is held in place by tension, but there is a metal insert in the rear upright section that is riveted to a spring clip in the top of the doorframe. Drill the head of the rivet off to free it.
