1. Before you toss that broken plastic trim piece, why not try to stitch it back together? Our Volkswagen Rabbit GTI came with a broken A-pillar cover. Since parts for these cars are getting harder to find, we decided to just fix what we had. Here’s our problem: an A-pillar trim piece that had snapped in half, perhaps from being tightened too much.

2. Start the work by roughening the back side of the repair area. A Dremel tool or just plain sandpaper works well.

3. Fabricate a splint of some sort from steel or plastic. Clean the area and mix up some quick-drying, two-part epoxy. Our personal favorite is Fasco Epoxo 88.

4. After taping up the good side of the plastic (the side that will remain visible), cover the back side of the repair i with the epoxy. Fill in the gaps from edge to edge.

5. Remove the tape to reveal your repaired piece of plastic trim. If using a dark-colored epoxy, you might not even need to paint. In our case, we hit the repair with a spot of putty and then dusted it with black trim paint.

ABS parts can be repaired with ABS cement, which bonds better and is more flexible.

ABS parts (which are most interior parts for the last 30-odd years) can also be repaired by melting ABS in acetone and then spreading on as a replacement for the epoxy.

That's how I repair my CRX fenders. Shred a chunk of ABS pipe, melt it in acetone and use fibreglass mesh (like drywall repair tape) for structure.
