OPGI Weatherseal Products – The Weatherstrip Report

Into each car's life a little rain and debris must fall, but with OPGI you no longer need to worry.

When restoring a vehicle, you can never “seal the deal” without replacing your weatherstripping. From the proper door, trunk, roof rail, window felts and sweeps, you need to make sure to use products that are built to exacting standards, and with Original Parts Group Inc. (OPGI) that’s exactly what you will find.

Automotive weatherstripping is essential in protecting your interior cabin from elements such as rain, snow, dirt, wind, or debris. Now, if you don’t know what weatherstripping is, then fear not; it’s the rubber material that goes along the edges of your windows, doors, trunk, hood, or body to help seal gaps. Typically held in place by screws, clips, adhesive, and/or by pressure, the seals help lessen interior cabin noise while also preventing dust or insects from crawling in. But if none of those factors are enough to sell you on replacing them. Then imagine a fresh paintjob with cracked seals; yeah … no bueno.

So when it comes time to source a new set of weatherstripping look no further than OPGI, a company that has long maintained a solid reputation as a top manufacturer of classic GM restoration parts and high-performance accessories. Found on many lowriders and classic restorations, OPGI has the largest collection of high-quality Chevelle, Grand Prix, Malibu, El Camino, Cadillac, Cutlass, Riviera, Monte Carlo, LeMans, and Skylark classic parts in the world.

In this Lowrider restoration article, we’re featuring an overview of the top-notch OPGI weatherseal products that have been meticulously designed with the utmost care and attention to detail. They are manufactured from premium materials, using the strictest manufacturing standards in turn, delivering unsurpassed quality, and a product that promises to deliver the ultimate satisfaction and performance.

With that said, here are just a few products from OPGI that are exclusively fit for the 1963-1976 Buick Rivieras. Now remember, take caution when you do replace your old, worn-out seals and be sure to remove any screws that your old seal had in place. From there, pry the old seals off by hand and remove any and all existing adhesive prior to installing your new weatherstrip. If you find old or rusted screws holding them in place, be sure to opt for a new set and apply a generous amount of pressure and let the adhesive dry thoroughly.

Besides all the authentic reproduction seals that OPGI sells for GM, this time around we chose to restore the weatherstripping on a 1971 Buick Riviera “Boat Tail” project we are currently working on at Lowrider Garage. Here’s what we chose to use.

1963-1976 Riviera Trunk Weatherstrip

Keeping your trunk dry is easy with a new weatherstrip seal from OPGI. This authentic sponge seal has been reproduced to OEM specifications and is designed to fit and function like factory originals. Weatherstrip glue is recommended for a proper installation. The trunk seals are universal in size and come with a little more length for a sure-fit size. Remove old rubber and adhesive from the channel or trunk gutter. Use adhesive and put pressure on your new seal as they are designed to fit properly into the gutter/channel. Allow time for your weatherstrip to set, as it is new and a little harder, until there is sort of a break-in period. Cut off the excess length with a pair of sharp scissors.
