[QUOTE="BJ James, post: 31862, member: 87"] Re: The "official" cabinet finishing thread I finally got around to redoing a couple 2x18 subs with Dura Tec. Like any other project, most of the time was spent in preparation. I removed all the hardware, masked off the drivers and cavities, and sanded the existing finish for a scuffed up surface. I used a palm sander to start with and found that it heated up the surface too much and gummed up my paper too quickly. I switched to a Porter Cable random orbital sander/polisher on a slow speed and a light touch. That worked much better. Then I mixed up some bondo to patch up a couple dings. Be prepared for a bit of frustration if you've never used bondo before. My first batch I used too much hardener and it hardened before I had a chance to do much. Next batch I didn't use enough hardener, and it never did cure properly and I had to scrape, sand, and acetone it off. Once you get the hang of it, it's easy. Use LIGHT COATS of bondo. After curing and sanding smooth, I spot primed the bondo'd areas and let dry overnight. Then on to the Dura Tec. This stuff is awesome. It's like a gel. I just used a brush to pick up a glump, spread it out on the surface a bit, and rolled it out with the Dura Tec roller. It dries quickly to the touch. Instructions say you can apply 2nd coat once it's dry, but I waited over night. It seriously looks like a factory applied coating. Very nice texture. I hope it holds up well because it will be a bitch to sand in the future. Tonight I will be able to unmask and reinstall the hardware. Then start on the next pair. edited to add: I keep spelling it wrong. It's Duratex. And also wanted to mention how easy clean up is too. Rinse brush and roller under a tap. Done.
