Hi i have been playing around with repairing brittle plastics and tried all the recommended glues, with very limited success. After a lot of googleing i found abs slurry which has seemed to work perfectly. strengthening the cracked and broken pieces and allowing the parts to be screwed back in without further cracking. It will be interesting to see how it performs over time.

My dash has unfortunately partially fallen apart, the shifter trim with the window switches is flopping about because one of the previous owner broke all the screw mounts and the ashtray is sagging because the left screw mount is broken.

One of the previous owners seemingly attempted to “fix” it by gluing everything together but that all came undone when I disassembled the shifter after my shift linkage failure.

As you can see i am rebuilding the screw hole by adding layers of ABS slurry until it forms a complete new area which is solid again. a piece of tape on the other side to set the starting level

Hmmm, I don't envy you that job.

Its pretty easy but very time consuming luckily being retired i have plenty of time

Its actually quite easy but time consuming. It needs a couple of days for the acetone to leach out of the ABS and possibly longer depending on temps, up here in the sub tropics its pretty quick. It can be up to 7 days in other climates but it also gives time to repaint the part as well

Am almost finished with redoing my interior. Used mainly JB Weld 2-part epoxy after stripping the paint. Found that roughing up the glued surface helps. One large epoxied area may have caused a further differential expansion split. Have used a lot of metal washer and strap reinforcements and bought a new center forward console instead of repairing that piece. Saw another thread that used a soldering iron to melt-fix the cracks. Found my worst problems were at screw tab connections where the parts had just crumbled. Semco primer and Volico paint and clear flexible protective coat for the surfaces. Didn't take many pictures during the process, but will show finished product. The original parts were the siam beige with a lot of ugly scrapes and scratches.

I used the jb weld but it didn't work all the convincingly for me and the good thing about slurry is you don't need reinforcing it is reinforcing in itself. But im glad you had good results with the JB weld

So pulled the main dash and started repairing it, new tabs out of 2mm abs and all fixed in place with abs slurry it has come up solid as a rock
