How To Repair Broken Plastic Car Parts


hey this doctor fast here and in today’s video I will be showing you how to fix broken plastic parts in a vehicle and this one here is a Chrysler 300m and what I need to fix is this door handle right here you see the trim is actually cracked right in half now to replace this a user1 is about 60 70 dollars quite expensive so I’m going to go ahead and remove this and I’ll show you how you can fix this and repair this to remove this door handle what you need to do is get a flathead and pop open this cover and inside here there’s actually a Philips screw let’s carefully remove this so this is what I had to do I thought the screw would have been able to release this handle but actually underneath at the bottom here this piece is actually molded to the door panel self want to being my mold is that there’s a plastic tab that sticks out and then melted it to the door panel self so I ended up sticking a soldering iron here just to melt that plastic to remove this now I can remove the door panel of course but regardless even if I had the door panel off I still would have had to melt that plastic tab at the back here to release this handle go ahead and disconnect this connector you see that blue tab this holds a metal rod you want to push this in to release the metal rod and then once you release it this middle hook you see it right there will come off so here I have the door handle here what you’ll need is also some fiberglass mat you can pick these up at automotive shops or some supply stores that provide some supplies for auto body and also you’ll need the epoxy now typically when you work with fiberglass you should use like a resin epoxy resin that comes in a big can but you know for a job like this you really don’t need to buy that whole jar so just get some sandpaper just go over the area that’s cracked or broken you need to do this all around anything that needs to be glued on later on just rough it up a bit and as the other side then get yourself a damp cloth and just wipe the surface clean it up to use the epoxy what you want to do is remove this cap that’s on the handle and this is actually for you to seal the tip when you’re done okay and then yourself some side cutters and you want to cut off the tip the first thing you want to do is to apply epoxy on both surfaces and glued together and also spread some epoxy on the inside surface as far as the outside surface keep it clean and make sure there’s no epoxy coming out and if there are just get a paper towel and just wipe it off hold it for about five minutes and let it set get yourself the fiberglass mat and all you need to do is cut some strips because what we’re going to do is I wouldn’t have gone this far but alas mat these strips of it onto the back of door handle and we’re going to use the epoxy to soak up the fiberglass mat onto the surface here so that is going to be used as a reinforcement to make sure that this does not break again so you can cut into pieces and just cut off the extra bits you may want to wear gloves to make sure that the epoxy and the barbed glass doesn’t get all over the place and get onto your hand okay here I’ve cut a lot of small pieces like this little piece of rectangle and I’m going to start putting these pieces over this inside surface but first we’ll need to mix more epoxy and this time you might want to mix a little bit more only because we’re going to do two layers of fiberglass so again you put the cap back on seal this up and go ahead and mix this mix it well we’ll go ahead and start spreading the epoxy onto the inside surface you want to do one section at a time well this is wet go ahead and grab your fiberglass just lay it down right in here it does get a little messy so that’s why you want to use gloves Pat it down like so then we’ll put some more epoxy on top you see this piece is soaked up with epoxy now just make sure you press everything in you know it’s put another layer here like this so now with two layers starting to set the until it’s getting really sticky and thick now so let this dry so we’ll do one side right now I mean this side and then we’ll work on the other side later on now we’ll mix up another batch okay so let this dry so I’ve waited about maybe thirty thirty forty minutes that’s when a fully cures and all you have to do is get a pair of scissors and anything that is hanging off the edge any extras just cut off the extra bits so from the front you don’t see it now we’re ready to reinstall this so first what you want to do is grab this rod and insert it into the hole then all you have to do is flip this blue patch over the rod I’ll lock it in place now we’ll connect up the power lock connector close the cap and that’s it so that’s how you can fix a broken part in a vehicle very inexpensively instead of spending a lot of money to replace a part anyways give any questions I’ll leave a comment below and if you liked the video please subscribe thank you
