Steele has a large line of high quality universal weatherstripping that’s perfect for building customs and street rods where direct replacement parts won’t work. We have extrusions made for sealing glass, doors, trunks and anything else you can think of!
Once you chop your build not only do you have to order custom glass to fit, you’ll also have to make your own gaskets to seal them up. Here are step by step instructions on how to cut and paste (or glue) your way to a perfect, custom gasket right there in your own garage.
Get ready for arts and crafts time!
Things you’ll need:
- A brand new razor- one from a standard box cutter will work
- Loctite Superbonder 495- we sell it here or you can ask for it at your local auto parts store
- Small dish to pour the glue in
- A paperclip
- Your gasket material (dense extrusion)- here’s a link to our universal products
- The glass piece you want to seal up
- Something to mimic the glass to fit the gasket ends on as a guide when gluing them together- must be the same thickness of the glass 3/16″ to 1/4″ (we used our plastic tuck tool)
Step 1: Measure– To measure properly, install the rubber onto the glass all the way around and mark the spot where you need to cut it. For the end result, you want the gasket to fit tightly but you don’t have to stretch the rubber to make the ends meet. *For a locking strip type gasket you’ll want around an inch of slack to give the rubber room to expand once the locking strip is pushed in.
Step 2- Cut. Take the rubber off the glass and cut it with a brand-new razor, pressing straight down on it evenly from both sides. Getting the cut edge perfectly straight on both ends of the gasket is key to get them to match up correctly.
Step 3- Line it up. Put something in the gap where the glass goes to join the two ends. We used a tuck tool.
Step 4- Spread your glue. Using a paperclip, spread a small amount of the Loctite 495 on one end, but make sure to coat the exposed face of the rubber all the way to the corners. You don’t have to glue the entire seal at one time.
Step 5- Press the ends together. Slide the rubber together slowly, using the guide to make sure everything is lined up perfectly. If the glue squeezes out, DO NOT wipe it away, let it dry.
***You don’t want the gasket to become glued to the guide. Once you see that the ends are sticking together, remove the guide right away. Superbonder 495 literally bonds things together making removal extremely difficult.***
Step 6- Spot check. Go back and fill in any spots not glued the first time.
Step 7- Clean up the joint. Carefully scrape off any excess glue (once completely dried) with a razor making sure not to gouge the rubber.
Step 8- Installation. Install your perfectly made custom gasket! The glue bonds the rubber ends together making an airtight, super strong seal that dries in seconds.
