Primer For Quarter Window Repair

  • Sponsors (?)


Hey guys, just out of couriousity. I was wanting to redo mine I have a 90' LX Hatch, but mine look like they are rubber and dont even look to be repairable(very cracked and deteriated). Is this the case with the ones you have referbished or am I to the point I just need to replace the trim. Thanks Chad
 
IMO, you can restore anything. The rougher they are, the more primer you will need. Honestly, I didn't sand much on a bad pair I had. I just hit them with 80 grit to loosen the cracked areas. Blow them off real good and go to town with the primer. Spray bomb primer will take forever. I literally used 2 or 3 cans on a pair one time and they still weren't perfect. I highly recommend Nason 2K Urethane primer. It's activated and you mix it 4:1. You can even thin it out with a little bit of laquer thinner. I do it all the time, but to get it to spray easier cause it's so thick.

I would spray 2 wet coats (wait 15 minutes between each coat @ 70* temp...longer at colder temp). I would let that dry at least 3-4 hours @ 70*...longer if colder. You most likely will still see holes/divets. Simply sand them down with 150...blow off...spray again...2 more coats. Usually...4 is a done deal. Sand them with like 320, then 400 or 600 spray them with your black paint/clear. Done deal. If they still have imperections...get more coats of primer.
 
Snow, a lot of times they do look like that. The only issue with the really badly deteriorated ones is that you lose the character line in the rubber. View attachment 141970

True, and you have to pay a lot of attention when sanding not to sand this line away. It was hard for me to sand this line and get the crevice perfectly smooth. I've still got a few bubbles here and there in that line, but nothing that people will notice.
 
Yeah, I think Ill just have to live with the crapy ones I have now and order some new ones later. I hate to have to order a complete new set just to have the rubber look good. My lines are already messed up so I guess no use in trying to make something look good that will take to much time and money and still probably wont look that good.
