rear deck surrounds
Hi Guys:
I have a'93 coupe and the black plastic surrounds on the rear deck that the shocks go thru have enlarged screw holes so the screws will not hold
Is there a way to fix the plastic with epoxy or something and re drill the holes?
thanks

plastex.net Most epoxys do not stick well to abs plastic, cracks and peels off after a few years. I've tried many different kinds. Another option is dissolve small pieces of abs plastic in acetone and make a paste. The plastex kits work well, I molded new tabs to replace broken missing ones. They have online instructional videos.

I had similar problems, as well as cracking on my pieces. I did some research on repairing old plastic, and came to the conclusion that the only way to repair ABS is with more ABS. I had a sheet of ~1/16" ABS. I sanded the back with 80 grit at the mounting locations which opened the holes up a little bit further but provided a nice uniform area to glue my ABS to. I cut pieces that fit on the backside where repairs were needed. I gooped the pieces up with ABS glue from the plumbing dept and used spring clamps and other various wood working clamps I had available to hold the pieces on while the glue dried. Then I simply re-drilled the holes and my repair was complete. It should be noted that ABS glue is basically acetone with ABS suspended in it. The Acetone evaporates and you're left with solid ABS. So if you don't have any ABS glue you can make your own with a little acetone as mentioned earlier.
Anyways, using this method I was able to re-pair/rebuild a bunch of my plastic pieces.

Also, abs should dissolve with acetone.
Also you can do a burn test http://www.boedeker.com/burntest.htm
I can do a test with my rear deck piece to see if it is infact ABS, although I'm 90% sure it is based on my repairs.

According to google there are few ways to narrow it down. One is to check it's specific gravity by seeing if it floats in certain liquids. ABS should sink in water.
Also, abs should dissolve with acetone.

No need for compensation! I'll see if I can determine for sure it's abs over the long weekend. Maybe I can even get some pictures of my repairs.
