How to Use the 6450 Bumper Bag Plus

Polyvance's 6450 Bumper Bag Plus is a versatile tool that works in many different areas of the body shop. Use it to take small dents out of plastic bumpers and sheet metal, adjust the fit of adjoining sheet metal panels, and even use it to cushion a jack saddle to eliminate the risk of damage to the subframe.

The Bumper Bag Plus is made from 70,000 pound tensile strength webbing and is practically indestructible. However, it is also soft enough to conform to the shape of whatever it is pressing up against. This allows it to take the energy of the force and prevent further damage to the area.

This product was invented by David Kilburn. Another of David's inventions is the Bumper Rollers kit, which is a great tool for removing dents from bumpers. You can use these two tools together or separately.

Always wear proper safety gear while working!

Hi, I'm Kurt Lammon with Polyvance. I want to introduce you to the Bumper Bag Plus. This versatile tool will allow you to remove small dents from plastic bumpers and even from sheet metal. It allows you to fix sheet metal panel fit among other things as well. It's made of a strapping material, very strong, with over 70,000 pounds of tensile strength. So it's virtually indestructible for its normal use. Just don't cut it with a razor blade. This product comes to you from David Kilburn. He's actually a full-time collision repair technician in Southern California, and we are proud to distribute his innovation to the collision repair industry. And for instructions on how to use this product, I'll let Dave take it from here.

Hi, I'm Dave. Today I'd like to share with you the Polyvance Bumper Bag Plus. You're gonna get a lot of use out of this tool, and we're gonna start right with the "Bumper Bag" part first.

As you can see all these imperfections where the bumper has been hit and here are all these dents. We're gonna knock these dents out really quick with the bag, and you're not going to use any heat. You won't be using any filler. You're just going to knock them out with the bag. So now what we're gonna do, we're gonna turn the bumper over and we're going to determine where the damage is on the back side of the bumper. So, you can see right here is a crease and I just want to mark it with my marker. Right here is another one of the dents, so I'm just gonna mark that so I know where I'm at. You can even actually kind of feel it with your hand. I'm gonna take the bag and I'm gonna put the bag under these marks. Now put the bag under the marks. What I prefer using is ball-pein hammers. I'm gonna come in here and I'm just gonna hit right on my line. Now when you get into a body line like this, I'll take a hammer like this, and you've got to remember not too hit hard because you will put a hole through the bumper. But you just wanna massage that line a little bit.

Now that you've hammered it out, turn it over and take a look at it. See how it looks. You can see that I drove almost all that completely out. Now I'm gonna take my sander with 80 grit. I'm gonna go over it with 80; I don't recommend anything coarser than 80. After I use the 80 I'm gonna use 150, and then I'm gonna finish it with a 320 grit on a DA sander. Now that bumper is ready to be primed. It's really that easy to go in there finesse out the dents, come back sand it, and you're ready for the primer.

Now that we did the "Bumper" part of the bag, now I want to show you the "Plus" part. How we're going to bend sheet metal and jack cars up and not damage anything. It'll make your job a lot easier.

So, when you're jacking a car up and you want to jack on the subframe, you don't want to damage the subframe from the saddle on the jack. The bag will form to the jack and the subframe; it will not damage it. So all you're going to do is put the bag on the jack, bring the jack in, and just go ahead and jack the car up right on the subframe. And it's not gonna hurt anything; it's gonna go ahead and form right to the subframe. So now you can jack up on a subframe or a suspension point without damaging anything. You can see here where the bag forms to the frame rail and to the saddle on the jack. This avoids the saddle hitting the frame rail and putting damage into it. And even though this is a plastic cover, you can still jack up there. It's not going to damage it because it's going to form around it.

The way this bag works - one of the magic parts about it is - it's extremely strong; the only thing that's gonna hurt this is a razor blade or fire. Anything else, you're not going to damage it. And when you hit it with something, it'll take the contour of what you're hitting it with, but it also will support whatever is around it. And that's one of the key factors. When I use it to bend sheet metal, which I will show you in a minute, it's gonna form to the sheet metal. You're not going to damage center pillars, inner door frames, hood frames, core supports, this is going to take all the abuse, and you're just going to massage all the parts.

So when it comes to sheet metal, if you have your fender off the car - which nowadays a lot of the shops where I work at, we paint all of our parts off the cars. You can see the crease in this fender, and I'm going to do the same thing I did with the bumper. I'm going to turn it over. So what I'm gonna do is I'm going to determine where that damage is, and I'm gonna take my marker and I'm gonna mark it. So the damage is right through here, and I want to mark this body line as well. So I'm gonna come back with my hammer, my sheet metal hammer, and I'm just gonna hold the fender on the bag like this. You don't have to hit it really hard. Now you can see what effort that took. That's probably ninety percent of it out right now. You could go from there with your filler.

You can see right here this car was in a front-end collision. The hood has been repaired but the hinges got bent. They've rolled back, and you can see how much lower the hood is than the fender here. So I'm gonna take the bag and like I said earlier, the bag gets kind of formed to every contour, it's gonna form to the contour the edge of the fender, the edge of the hood hinge, and the frame of the hood. We're not gonna damage anything; the bag is gonna take all the abuse. And this is a finesse thing. Body work is a very manhandling thing - you want to finesse this. If you don't finesse it, you're gonna bring the hood way, way up too far. So all I'm gonna do is I'm gonna put the bag right here. Don't be concerned about any of this stuff; nothing's gonna get damaged. All I'm going to do now is I'm gonna take the hood and again, very gently, rock it like this. You might take a couple times to do it, but you don't want to overdo it. Now that brought it up some. I'm gonna go ahead and do it a little bit more. I'm gonna rock a little bit more this time because I got an idea where I'm at. Now you can see how it brought the hood back up with the fender. Like I said, you're better off starting slow and then do it a couple times. That takes no time at all.

If you get a hood that you cannot get to fit the fenders in the front, where the hood is sitting too high on both ends, take your bag and you go ahead and place it right here on your core support - not on the latch - on the core support. Let the strikers on the hood hit here. And you'll get one guy here and one guy here and you both can push down like this and actually put an arc in the hood and get the hood to fit the fenders. When you have a hood that gets a low spot in this area where the hood is fitting good here and fitting good here, but it's low in the center, all you do is you take your bag, put your bag like this, take your hood, and you just take it and rock it like this. It takes very little effort and you'll bring this whole section of the hood up and it will align with the fender, and it will help bring the fender down as well, because it's doing both things at the same time.

You can see here this door, it has a twist in it. The top of the door is out and the bottom of the door is in. So I'm gonna take the bag and I'm gonna take the bag and I'm gonna place it in the bottom of the door. The bag is gonna go to the contour of the door, the pillar, and the rocker; you're not going to damage anything, the bag is gonna take all the abuse. So you're gonna put the bag in here and you just take the door you're gonna rock it just like this, and that's how you're gonna take the twist out of the door.

I hope you now see the benefits of the Bumper Bag Plus. If you have any innovations in the realm of plastic repair, please contact me. It's possible we can work together to bring your innovation to the market for the benefit of the collision repair industry.
