Rust pin holes can happen on vehicles as new as a few years old in some cases. You might not have the money to pay an auto body shop to perform the repair or the tools to cut and rkst a new patch panel in. But there how to finger my girlfriend solutions that will give you a simple repair weldint can be done in your driveway. Below we show you the process for repairing rust pinholes and sealing the area up for a permanent repair.
In the very center of the bubble is usually the worst of the rust and you can test the area by tapping a screwdriver on the area to see if it punctures the surface. You can sand the surrounding area lightly to see how far the rust spreads and ruet where the rust hole starts and ends.
This is the area you need to replace. This method will knock out the rusty metal and give you a clean hole that you can work off of. If needed you can cut around the hole with aviation or tin snips to make it larger to get into rust-free metal. You can then use a file and sandpaper to file the hole and remove any burrs in the metal. Start by drilling a small hole in the center of a backer and lay it over the rust. Hoow can then trace the hole on to the withot with a marker.
Next, cut out the area you traced with scissors or aviation snips; leaving a little extra material weldung the edges. Now you can insert the pin into the backer and test fit it in the hole to make withotu it will fit and trim as necessary. Mix the epoxy and apply it to the front side of the wituout and the center pin.
Immediately after applying the epoxy to the backer you can insert it in the hole and pull it up until it is tight with the original panel and slide the retainer clip over the pin until it touches the metal and firmly holds the backer in place.
You will want to leave the clip how to cook sambar at home backer like this until the epoxy fully sets up and cures. Once the epoxy has fully cured you can cut the pin off of the center of the backer and sand the area with 80 grit sandpaper to smooth out the epoxy and the surrounding area.
This will leave you with a surface ready for body filler. Makes sure you feather out the filler beyond the repair so you can sand it all level in the next step. You can then block sand the area going from until the repair is blended into the surface of the panel. At this point the repair is smooth and sealed up and you can block carac cream how long to use and perfect the repair if fust desire.
If needed you can then apply paint and clear to the panel and blend it into the original paint or paint the entire panel. You must be logged in to wepding a comment. Top Selling Products.

Thanks to modern chemistry and manufacturing, we now have two-part epoxy panel adhesives that are strong and flexible enough to bond metals together more or less permanently. I had a major rust problem in my Mitsubishi Montero LS V-6 four-door and thought giving glue a chance would at worst demonstrate what not to do, and at best bond some new steel in place of rust with a minimum of body filler.
Having tried everything from trusty old Bondo to welding in steel, this was my first time using panel adhesives unless all those tubes of Testors model cement count. And, to quote Airplane , it really was indeed the wrong week to quit sniffing glue.
My target here was non-structural steel-to-steel repair, the expected end result being somewhere in between exquisite hand-hammered Italian coachwork and the standard New England Tiger Hair skimmed over expanding foam hack and pack. Welding in patch panels with a flux-core welder without a gas envelope is an exercise in burn-through and swearing—so glue it was.
And maybe the epoxy would result in a more rustproof seam. The first step was to cut out the rust. Following some quick work with a Sharpie and cutoff wheel, a perforated steel and Bondo sandwichs littered my workspace floor. Next up I used a pneumatic flanging tool that clamped its offset jaws onto the steel and gnawed around the hole so the steel patch had a recessed contact patch to sit flush in the adhesive for minimum body filler work.
Once the patch area was ready it was time to cut some paper templates to create the steel patches. As there are no ready-made patch panels or skins for the mighty Montero, I fabbed up some one-off templates with a Sharpie, poster board, and protractor for angle measurements. I then used the templates to trace out the patch panels on some sheet metal. After slicing the patches out with a cutoff wheel, next came the bending, hammer, and dolly session until the patches matched the holes and fit snug and flush into the flanged seat.
I used a piece of PVC pipe, a vice-mount miniature metal break, and body hammer kit. Test-fitting with clamps was up next. Working with two-part epoxy adhesive can range from quick to slow, so my plan was to have all the clamps ready to rock once the two-part adhesive started flowing. We used every clamp I had access to, from Vise-Grips to hose forceps with some masking tape on the contact points. My prevailing theory was that masking tape would be easier to grind off the metal than a clamp.
Probably overkill, but there is a second flat U-shaped steel patch on the backside that made an epoxy and steel sandwich of sorts. Self-tapping screws came in handy for fender well patches. Cure time was hours on this stuff, so that was that until the next morning. Come the next day, I dropped the clamps and the repair was solid. After some grinding with a grit resin sanding wheel on a four-inch grinder, the patch was ready for a skim coat of body filler, primer, and finish paint.
One advantage to panel adhesive over welding is that the lack of heat that can warp steel door or quarter panel skins. Another bonus for adhesive over welding is the potential bonding of dissimilar materials. Fiberglass fender flares or an aluminum NACA duct to a steel body, for instance. The adhesive I used is an Evercoat product that came in a single standard size tube.
The caulking gun struggled but the mixed adhesive eventually flowed. Other products use a dual tube setup that requires a matching gun. Choose your weapon and bond away. Was it easier than welding? Yes and no. Certainly different. I am by no means a fabrication expert—my bodywork skills were developed from time spent in the Set Painters Union sanding Bondo for the International Alliance of Theatrical Stage Employees.
The first time no-weld metal repair has held through a few hundred miles of extreme cold and two winter storms so far. Time will tell just how well it holds up. It is not the right repair for every situation, but sometime it is just the repair that is needed. Never bad to have one more way of doing things in your knowledge arsenal.
