    FYI this is available in spray type as well for those of you with spray guns.
    I have several spray guns from 1.2mm tip up to a 2.3mm tip, but I think rolling that stuff is better to get a textured finish. Spraying would limit the texture control. Pretty cheap stuff. Any paint would cost twice that even for low end paint

    I wish I would have found out about Duratex before, makes the finishing process soooooo much easier. The gallon goes a long way as well, have finished 2 6.5cuft subs, 8 cuft and a small platform to elevate my TV a little more and still have a little over a half gallon left.

    One of these days I am going to experiment on a piece of scrap with applying maybe 4 coats of Duratex with some light sanding in between each coat to try and get as smooth a finish as possible. Then I will let it fully cure for a week or more before lightly sanding and buffing for a gloss finish, anyone ever try that?

    If you are going to do all that, and you want a gloss finish, you might look into automotive paints. Especially if you have the capability to spray. It would go alot faster. Essentially what you are describing is using the duratex to achieve a smooth finish when there are other things that would do that in a single application, like a primer surfacer
    I once painted 80% of a GMC Yukon with only 2 quarts of base coat. Most black paints cover in darn near one coat. Not cuite, but almost

    There is the rub, I don't have or want to go into setting up a spray rig. A friend of mine has a spray rig I could use but it is just something I do not like to do, I would rather pay someone to spray on a finish. I don't mind rolling on the Duratex though and even though I know it's more time consuming it relaxes me which is the opposite of spraying which aggravates me.

    I have never been a fan of the finishing portion of DIY but with Duratex it is so easy I don't mind anymore. That was never the case when I tried spraying even though I came out with good results I just always have hated the process.

    Plus, Duratex has no harmful fumes...It smells like NOTHING. You could use it in your dinning room although that probably wouldn't earn you any points with the spousal unit. My wife hates me when I use rattle can paint. Having an attached garage ain't all it's cracked up to be.

    Bryan is correct about the fumes. I used it in my basement without any issues.

    I want to say that I've SPRAYED duratex before out of a hopper as per their directions. GO FOR ROLL ON!!! I wish I would have just rolled it because I think I would have had a better opinion of the stuff. It probably goes a longer way rolled on and can look better in the end.....spraying it was a pain!

    Did you thin it? The pic of it being rolled on was obviously way too high in viscosity to spray through any gun not designed for house paint.

You can get an aggressive high-build texture with a nappy roller or a fairly smooth texture with a sponge roller. I'd recommend you sand the first coat as it will make your minor cabinet imperfections disappear. Then your second coat will make your baffle/cabinet look like perfection. Just one other tidbit of advice: If you use Bondo on your cabinets, you will need multiple Duratex coats over that area, and sanding in between helps a lot. Duratex doesnít like Bondo, but it will work just fine with a couple coats.

    A lot of folks use a router, circle jig (Jasper or Router Buddy) and a 1/4" spiral bit. Others will use a rabbet bit for the rebate. You will have the best results if you use a bit made for plunging (i.e. not a normal straight bit like you'd use for a dado).

    Thanks. Plunge router + 1/4" spiral bit + jasper jig + careful measurements.

    Just FYI - it's common practice to NOT quote posts with long strings of pictures like mine. It takes up way too much room in the thread and makes people bitchy. If you hit "Reply With Quote" you can erase the code with the pictures and only quote the text......or you can just reply to the thread without quoting my crazy long picture post. Just sayin.....before somebody else does.

    Got it. Thanks. I have a router and SOME bits. I'll have to experiment on scrap. I dont actually belive it makes a notable difference in sound but it sure looks clean as hell

    For tweeters it absolutely DOES make a difference. Surface mounting a tweeter (as opposed to flush mounting), especially one with a thick flange will cause ripples in the frequncy response.

    That's a damned good question. After a week or so the finish is incredibly hard - almost like plastic. It's water-resistant too, so I'm not sure about how well it will allow paint to adhere to it.

    Are you considering buying this stuff if it can be painted?

    EDIT: I just realized they also sell it in white. I'm sure you can tint the white to any color you want. Maybe send them an email to confirm??

    yes. the method i used in the past is called armorthane. very tough and expensive. for my current build, it would probably cost close to $200.
    this looks like a nice option. i think i might try the white.
