Plastic Welding Door Panels?
Has anybody tried or know of someone who tried plastic welding cracked door panels? If so, were the results satisfactory? I've been considering buying a plastic welder for some other projects and today it occurred to me that this might be a way to save some otherwise decent panels from the trash heap if they could be welded from the back and still look fresh on the front.

For repairs on the back side, I suggest investigating a two-part epoxy if it is just cracked and maybe using sheet styrene or ABS to bridge the crack for extra strength. A two-part syringe of the stuff mady by Loc-tite sells for about $5... quick acting but I like to leave it overnight so it is rock hard. |
Yeah, 84, I figured on working the back of the panel where the crack is.
HIO, I've tried epoxy before (years ago), but didn't get a good bond. Maybe I needed to clean it with PSP like you would before dying or painting them. Anyway, I was just brainstorming today while I was working and thought about this. I'll have to give it a little more thought. Thanks, guys. |
On those door panels I just did. the trim ring around the brushed aluminum was ABS and I glued it to the door using ABS cement. Lowes sells it for like $5 a can. You can mix some abs shaving into it to make more of a filler material if you want. It chemically melts the ABS together so its one solid piece after, unlike glue.

To get a good bond, lightly scuff both surfaces with 220 and bridge the gap with some scrap. I fixed by grill inserts and have gone wheelin' a few times without the cracks reappearing.
Formulations have advanced over the years. I suggest ya try epoxy one more time - better to try with a $5 tube of epoxy than an expensive plastic welder that may or may not result in satisfactory results. Good luck pal. ~HIO |

Anyone have a dealer for the rear panels in a crewcab?
|
I know I can buy new ones, but on my daily-driver/workhorse, I just don't want to drop the coin right now. I'm still spending money on getting my Crew's paint and body work finished. I've also got two perfect sets in different colors, but they're for other projects and my old gold F-150 isn't treated gently all the time so I don't want to ruin a perfect set on it. At least until I replace it as my workhorse.
Blue Mongoose, you'll have to find a set of those. Nobody reproduces rear door panels for a Crew Cab. |
i just fiberglassed the back side of my cracked panel and it seems to be holding up great
|
Fiberglass, now that sounds like it would work great.... anyone got pics of that type of door panel repair?

Baking Soda and Super Glue Trick . . .
I'm curious what type of plastic these door panels are made of?
Anyway - here's something I accidentally stumbled on a few days ago on Yootube. The "Baking Soda and Super Glue Trick". It was being done to cleverly repair a worn-out fret on a antique guitar from the 1940's or so. Basically, you mix superglue with baking soda and the soda acts as a catalyst, turning the mixture into a hardened plastic that can be sanded and filed etc. I was thinking this could be really useful for repairs such as these door panel cracks that everyone here is talking about and could be an inexpensive fix. They say a medium viscosity superglue works best. Might not be for "concours" restorations but might let you keep using your own door panels for a long time to come and save some money. Can it be colored or touched up or a little dye added? What the baking soda does is to act as a catalyst instantly hardening the superglue into its plastic form upon contact. This plugs holes, seals gaps, and it has high durability. So using the medium glue, apply just a tiny little dab right at the end of the holes. Add a baking soda and make the surface intact by slightly pressing on it using a cloth or any material you prefer. Wait for a few seconds to dry. Then all done!
