Reconditioning the molding on fox rear quarter windows ?
 

So the trim/molding around the quarter windows on my 87 gt are getting old. They are starting to really dry out and pit. Before forking out some cash to get new moldings or moldings+windows has anyone here ever reconditioned the trim themselves? If so could you please go over the steps that you followed.

Thanks!

This is a post from somewhere long ago I saved. I've never done it so I can't say how well it works, Credit to the original author not me!

For anyone else who's had the inevitable "rotting" of the rubber moldings around the rear quarter windows on fox Mustangs, I have found a solution. Head over to your nearest Home Depot and purchase a can of black "PlastiKote". It's the stuff that's sold to dip tools and such in to give them a rubber coating. I did the following: Mix 3 parts PLASTIDIP to 2 parts naptha (recommended solvent by the manufacturer and also available at Home Depot) to get a sprayable mixture. Use 220 grit sandpaper to scuff the surface of the existing molding. Use Prepsol (or laqueur thinner/naptha) and a lint-free cloth to wipe down the entire surface after sanding. This should also remove any oils or silicone sprayed on the part in months/years gone by. Mask the painted surfaces around the molding. I didn't bother masking the glass as I just used a razor to scrape off any overspray. Spray on 3-4 coats, allowing 5-6 minutes of drying time between coats. This stuff dries very quickly and seems rather resistant to running so I applied heavy coats. I used an air compressor and auto touch-up sprayer (also available at Home Depot), but you can also use a cheap spray gun made by "Preval" (again, available at Home Depot) that uses disposable cannisters of compressed air to propel the paint. The results were exceptionally good. It would take serious scrutiny to even tell the parts had been "painted". The rubber coating looks and feels like the original. It also seems to do a good job of covering scuffs/blemishes on the black bumper/door moldings. In summary, it only took about an hour from start to finish. The materials were cheap...about $10 for the PlastiKote and naptha and less than $10 for the disposable sprayer if you go that route. The touch up sprayer that I bought for my compressor (also at Home Depot) was only $35. You'll likely have half a container of the plastic stuff leftover. I used it to coat my battery terminals, repair a few blemishes on my bumpers, and seal a few air leaks around the doors/windows. This stuff is the best thing since sliced bread. Cheers, Chris --

Theres a great mustang restoration website as well for buying the parts.
