280z Body Side Molding – Inserting the rubber molding

Finally found some time to start inserting the 280z body side molding!

Last time I riveted the 280z side molding channels onto the body. Now it’s all about inserting the rubber molding. I ordered the 5/8″ rubber molding from CustomAutoTrim.com, and it came to my door in decent time. The size, perfect. The installation? Prepare to take some time to insert the rubber molding. It took a good 30mins to put on just one rubber molding!

What you’ll need to install:
1) 5/8″ Vinyl / Rubber molding (see previous post about 280z body side molding for sizes)
2) Razor
3) Something thin / plastic like a spatula or a guitar pick
4) Tape measure

First, making sure it’s sized correctly! Last time, I ordered in the incorrect one… This one from CustomAutoTrim – perfect.

“Measure twice, cut once” – no no, measure three times. Whenever my mom was showing us how to cook, she’d always say, ‘you can always add, but you can’t take away’. The methodology is still true here, but reversed – you can always take away, but you can’t add. So measure w/ a little excess, you can always trim the molding later. And since I ordered 16ft of molding, I should have some excess…but only for trimming, not enough to complete another channel if i completely screw up.

The vinyl / rubber molding is a tight fit, and getting in that channel can take some time. Here i’m using a guitar pick to help feed the vinyl / rubber molding into the 280z body side molding channel.

Another technique i found to work really well in getting the molding on was to bend the molding like the picture below. This actually allowed me to use the molding itself to help press fit it into the channel.

At the end, i was only left w/ a 1/4″ excess.  A razor helped create a clean edge to butt up against the molding darts ends. Don’t mind the dirty car… after giving a nice wash and wax last sunday, i parked it in lot that ended up getting “cleaned”… meaning leaf blowers. ugh.
