How To Determine the Gap Size on your Weatherstrip

When it comes to your classic car, truck or hot rod Steele has weatherstripping for all applications.

For a lot of vehicles, there are OEM replacements that fit like originals and you can simply order those, install them and you’re all sealed up and ready to go!

But some folks have a car that didn’t originally come with weatherstripping or they can’t find an OEM style part to fit and that can be very frustrating. That’s where our universal line of weatherstripping comes in. We have hundreds of extrusions, each one can have several different applications and with these, we can help you find a solution for a piece that doesn’t even exist!

For example, if you have a 1930’s car that didn’t come with any weatherstripping on it, you’re still gonna want to seal that up and keep the wind noise and rain out. We have many different sample packs available that contain small pieces of our weatherstripping in them. You can test them out, see how they fit up against the jamb and even shut the car door on it and do the dollar bill test.

The dollar bill test is when you shut a dollar bill in the door and pull on the end of it. Its ok if the dollar moves a little bit when you tug on it but it shouldn’t move too much. A loose dollar bill indicates weatherstripping that’s too small and not sealing properly.

Once you figure out which extrusion works best for you, you can reference the part number on the card included in the sample pack, contact us and order as much as you need of that particular part number. Super easy.

And then, there’s silly putty. Yes, Silly Putty. This is actually a really cheap and easy trick to use to figure out what kind of gap you’re looking to fill. Let’s say you’re looking for door weatherstripping for your 1930’s car again. To figure out the space between the body and the door take your silly putty, roll it into a ball, press it into the jamb and shut the door on it.

Open the door and carefully remove the putty and you’ll be able to see the exact shape of that space, measure it and compare it to different weatherstripping profiles to determine the exact extrusion you need. If you’re worried at all about making a mess, just wrap the putty in some saran wrap- NO MESS!

 

This method doesn’t just work on cars- it can work anywhere you have a gap you need sealed up tight!

You can find all of our universal extrusions in our Universal Catalog but you can also find bumpers, grommets and plugs in there too! They’re listed on the page with dimensions for each so it’s easy to find the ones you need.
