Bondo Self-Adhesive Body Patch, For Large Rust-Outs and Damaged Areas, 2 Patches, 5.9 in x 5.8 in, 2 Patches

Let’s be real. If you’re dealing with rust this bad, you’re probably in for some frustration. A full repair usually means cutting out metal and welding in a new piece, which isn’t exactly a casual weekend project. Enter these Bondo Self-Adhesive Body Patches. Without them, my repair simply would not have been possible. Stronger Than You Think (With the Right Filler) If you’re worried about durability, don’t be. When paired with a high-strength filler, this patch doesn’t just “hold up.” It reinforces the repair to the point where it’s as strong, if not stronger, than sheet metal. The patch gave me a structure to work with so I could push filler deep into the area, making the final result solid. If you’re using the right products, this isn’t just a temporary fix. It’s a legit repair. Adhesion Could Be Stickier, But It Works The patches do have an adhesive backing, but I wish it had a bit more grip. Something a little gooier would have made placement easier. If your surface is less than ideal, and mine was far from perfect, you can still make it work, but you’ll have to finesse it. One trick is weaving multiple patches together to reinforce the structure before adding filler. Will This Work for Your Repair? My rust spot was massive, probably pushing the limit of what this product was meant for. Almost too big, but not quite. Ideally, you catch rust sooner than I did, but even for larger areas, layering multiple patches can absolutely work. That said, placement matters. If your rust is in an area that’s impossible to place a patch on properly, you might have a problem. But since these are super cheap, it’s worth buying some just to see if they’ll work for your repair. Worst case, you’re out a few bucks. Best case, you avoid welding and a massive repair bill. Bondo Compatibility is Perfect The Bondo stuck to this like a dream. I was able to layer it on smoothly and even push it deep into the problem area for extra strength. Without these patches, there would have been no way to make this work. Final Tips & Thoughts • Reinforce by weaving patches together. This helps create a stronger structure. • Test fit first. Since the adhesive isn’t crazy strong, positioning is key. • Use a high-strength filler. Regular filler alone won’t be enough. (I reviewed the one I used, so check my profile if you need recommendations.) For small-to-medium rust repairs, this is a game-changer. For bigger spots, you’ll have to get creative, but with patience, it can work. If I managed to pull this off with zero experience, trust me, you can too.

Worked well to patch up some small holes for rust repair.

So I had to rebuild the wheel well on my 02 Silverado due to rust. The rust ate through both the seam of the inner wheel housing and the outer bed panel where they come together and are welded. This is a common problem. If enough of the seam can be salvaged and treated with rust converter, you can use these patches/mesh to rebuild the seam and repair the entire damaged area. I used the old structure as a scaffold to hold the patch/mesh after I used a straight edge like a right angle ruler to recreate the seam. It worked great. Then I used the vertical flange of the new mesh to stick to the inner vertical wall of the wheel well until I was able to use fiber glass to hold it in and start the reconstruction process between the fiber glass and filler: fiberglass for the primary filler and structure rebuild and filler for 1/4" or less resurfacing for painting. I created a how to do video on youtube. The job came out great and saved me from having to purchase GM only supplied bed panels priced at $1200 each and wheel wells at $400 each. The only complaint I have is that the patches are not sticky enough to hold on to anything. So it was a waste of time to add this feature. The sticky side should stick to most anything to add value.

I bought this self adhesive body patch to build my custom Ghostbusters Proton Pack. I heavily modified the pack. I basically cut the main part of the body in half, removing a 2" wide chunk of material across the whole thing. When I was done hacking it up, there was a huge gaping hole. There wasn't any structural integrity. I used this material to back up the U-POL 7061 flexible body filler that I used. (The body of this pack is a flexible material like a plastic car bumper). This patch material was easy to cut and easy to shape. As you can see I had a lot of curves and odd shapes to fill. This patch material did an excellent job of keeping shape and staying put while I applied the filler. I am very happy. Just look at the end results in the pics. I could not have done this project without this self adhesive body patch. Good stuff!

Didn’t really adhere to the metal sheet but with some extra glue it got the job done

I used these but found the adhesive is pretty much a joke. When they were held or pushed in place and then body putty was applied they were wonderful. Once the putty dried they stayed in place without question. Even with bare metal and preforming the mesh it didn't hold very good. Overall its work the money if you need to cover a larger hole, and for durability it has been stable. The size is a bit small for me, but I am trying to cover gaps of 1/2 inch to 1 inch and 8 inches long. Its farily simply to use - grind to bare metal, clean, apply - but it just lacks adheasion without extra help.

Good placeholder and starter for large patchjobs

Overall, I've used this product countless times, and it's quite easy to use, durable, and of good quality. Overall, a good product. The only thing I've never found that I think is really good is its price.

Started grinding the side of the car and it started to disappear. Popped these in place and started to add the fiberglass filler over it. Worked great. Holes all gone and it's super strong. Sheets are easy to cut and shape, you may have to hold them in place temporarily , but the do have adhesive on them.

Easy to cut and relatively simple to shape to fit. Very stiff screen. Holds bonds well. Cuts easily with a scissors.

Worked great for reinforcing the missing pieces of my wheelwells after derusting the underbody of my minivan. Adding this to the process is like using rebar with concrete, giving structural integrity to your body repairs.

used black window sealer to stick to metal of car roof adhesive lacking heavily

Good product, did the job!! Recommend & would buy again.
