BLS Posted January 2, 2004 Report Share Posted January 2, 2004 Im not sure where to ask this but do any of you know where i can buy some Conductive Shielding Paint like the stuff Here but cheaper? I dont feel like spending 30 bucks on that stuff. Quote Link to comment Share on other sites More sharing options...
jbkim Posted January 2, 2004 Report Share Posted January 2, 2004 Hmm... all the other source I found are industrial. How much do you think it should be? Quote Link to comment Share on other sites More sharing options...
MikeB Posted January 2, 2004 Report Share Posted January 2, 2004 im sure ive seen the stuff somehwere else, but i cant remember!! 30$ is OTT! Quote Link to comment Share on other sites More sharing options...
jbkim Posted January 2, 2004 Report Share Posted January 2, 2004 Did you want to use this stuff in conjunction with copper foil (in the hard to reach spaces) or in lieu of it? Quote Link to comment Share on other sites More sharing options...
Saber Posted January 2, 2004 Report Share Posted January 2, 2004 I tried local music stores but all they carried was copper sheilding tape. They suggested trying local lutheries. Someone at MIMF mentioned an alternate product named Slip Plate. It's an industrial coating that contains graphite but I don't know where it's sold.

bluespresence Posted January 2, 2004 Report Share Posted January 2, 2004 The conductive paint I have found is expensive everywhere so I've gone to using aluminum tape. The factory PG's are lined with it and some factory and custom cavities I've seen also use it instead of the copper. Aluminum is actually a better conductor than copper and is more readily available. You can pick up 3" aluminum tape at the hardware store for $4-5 for a 30 foot roll. It seems to work as well as the copper in my experience. It quieted a "hummy" strat down I had (G&L Legacy) with pretty good results. It didn't clear all the hum up, but I'm not sure anything would have. That thing had some HUM! You may want to try it. It's cheap, easy to get, easy to form in the cavity and if it doesn't work for you you're only out $5. Just a thought. Quote Link to comment Share on other sites More sharing options...

It's an industrial coating that contains graphite but I don't know where it's sold Slip Plate can be found at a hardware store or lawn & garden dealer. The John Deere brand comes to mind but there are others. It's messy, more like a lube than a paint. It comes in spray cans like paint. It's about $5-8 a can. I use it on my mower deck to keep the grass from sticking - never thought to use it on a guitar. Quote Link to comment Share on other sites More sharing options...
daveq Posted January 2, 2004 Report Share Posted January 2, 2004 Aluminum is actually a better conductor than copper This is a bit off topic but I'm interested in where I can find information on this? Here's what I found (they both seem to indicate that aluminum is about 60% less conductive than copper). Although its electrical conductivity is only about 60% that of copper, it is used in electrical transmission lines because of its light weight. from Aluminum vs. Copper Aluminum also has a rather high electrical conductivity, making it useful as a conductor. Copper is the more widely used conductor, having a conductivity of approximately 161% that of aluminum. from Second Page Not a big deal, but I was wondering if you were talking about an alloy or something that made it more conductive than normal aluminum.

Saber Posted January 2, 2004 Report Share Posted January 2, 2004 It's messy, more like a lube than a paint. From the Slip Plate Website, there appear to be several types of the stuff. According to them, Slip Plate #3 dries to a "hard thin coating". Maybe that's the one. ????? However Slip Plate #1 contains the highest percentage of graphite so it would shield the best. ?????

MikeB Posted January 2, 2004 Report Share Posted January 2, 2004 but if i can find any of that paint cheap i think thats the way ill go, it does a neat job, in my ibanez control cavity. Quote Link to comment Share on other sites More sharing options...

Yeah, you guys are correct. I always thought the aluminum was better, but I poked around on your links and some others and found out otherwise. Makes sense (and I don't know why it didn't before ) because you always use 2 sizes bigger or more aluminum wire when wiring service drops to a house. I'm always learning!

Drak Posted January 2, 2004 Report Share Posted January 2, 2004 This is information I've read from other sites in the past on discussions just like this one about copper vs graphite. They reported that the graphite paint, per 1 coat, is only about 25% as effective at shielding as the normal copper tape is. So as long as you apply 4 coats, you've equalled the tape. I tried the black paint once, but I've used the copper tape for everything since then. I personally really like the tape, and all of my guitars, being pre-amped now, really really need the best possible shielding I can provide, so I go with the tape. And they have all turned out dead-quiet for the most part, even under boost. Also, I have read that the 'secret source' of copper tape is stained glass supply houses. I haven't tried looking for it there yet, but that was a tip someone posted once. They said Much cheaper there. FWIW. Quote Link to comment Share on other sites More sharing options...

westhemann Posted January 2, 2004 Report Share Posted January 2, 2004 i just bought some of that conductive paint from stewmac.it is great stuff.spreads well with a brush,dries quickly,and that $30container will sheild about 20 guitars or more is my guess.and it only takes about 5 minutes to "install" my opinion is it is a time saver over copper Quote Link to comment Share on other sites More sharing options...

I haven't tried looking for it there yet, but that was a tip someone posted once. They said Much cheaper there. I have also read that some copper tapes aren't backed with conductive adhesive like the tape sold purposely for shielding, so you have to insure electrical continuity between the foil pieces by connecting them with dabs of solder. That's also why aluminum tape might not be as good a solution as copper tape since solder doesn't stick to aluminum. Quote Link to comment Share on other sites More sharing options...

Good point. I would guess the stuff you might find at the stained glass houses will probably fall under this catagory too. Quote Link to comment Share on other sites More sharing options...
Brian Posted January 3, 2004 Report Share Posted January 3, 2004 Those are all valid points and your close Wes I average about 35 guitars with one of those little cans doing a double thick coat. 4 seems like overkill to me (overkill i/e shooting rats in the back yard with a 50 caliber) Quote Link to comment Share on other sites More sharing options...

BLS Posted January 4, 2004 Author Report Share Posted January 4, 2004 Yeh that the problem i only need to coat 2 guitars not 35.. can i get a smalelr amount? Quote Link to comment Share on other sites More sharing options...
jbkim Posted January 4, 2004 Report Share Posted January 4, 2004 Yeh that the problem i only need to coat 2 guitars not 35.. can i get a smalelr amount? I wonder what the shelf life is for that paint. Is there anything on the label, Brian? I know I'll have owned or worked on at least 35 guitars within my lifetime .

Brian Posted January 4, 2004 Report Share Posted January 4, 2004 Indefinate shelf life since the base for it is water so if it dries up just add a few drop's and stir Quote Link to comment Share on other sites More sharing options...
