Um... I don't hink thats stuff is electrically conductive so if you cove and important connections then your board is toast. How about you just don't spill water on it.

Not that particlar product, but yes , something that was real similar.

Krylon(i'm sure) use it make an aerosol that when applied had a bright burnt orange color.
It was a good protectant for weather and insulator for lite contact.
We had to seal electrical componet covers w/silicon but if the bottoms(say a regulater)
was a circuit board we would use the Krylon product on it. Two applications.
It was used on heavy equipment that saw all weathers.
Krylon's site does not list it. The last time i used a can was 15years ago.

mcmaster.com page 661, take a look. Kind of expensive.

I obsconded with a can of the Krylon product but can't find it. Prolly thrown out, due to age.

The next order i have at SVC a can will be bought. As that type of product is the hot-set-up
for old motorcycle circuit boards. I got two old Eye-Ties that should be put back in service.
Thanks for posting this.

I guess if you took it seriously, and sealed off the processor socket, ram socket, fan sockets, ports, power sockets, ram sockets, chipset sockets, and every other damn thing that shouldn't get covered, you could do something like this with quite a few products.

I'm guessing you're doing a watercooled setup and want to protect against leaks?

I think the potential for a large mess is high .

Yeah. You're welcome, Galvanized.

Markbnj -- Wise observations. And think about it: you can't coat the PCI gold-conductors where they make contact, so depending on the severity of a water-leak in a water-cooled system, it probably might not help. Might reduce the probability of damage, but it wouldn't eliminate that probability altogether.

So if one were going to make a water-cooled setup, how much trouble would it be? You'd have to cover all the mobo pins -- USB2, game-port, front-panel LEDs and switch pins, AGP/PCI-E, PCI/PCI-x, fan 3-pin pinouts, ATA/IDE, SATA2/150, memory slots (don't forget those!) -- lots of tedium there.

You couldn't leave the CPU in its socket without covering it: you don't want this stuff between the CPU and your AS5/HSF. You probably wouldn't want it on your HSF.

But for old-timers like us, who have the time to mask off all the things you don't want to spray with it, and the mobo is laying there on the bench, brand-new, just waiting to be installed . . . .a-a-nnd . . . A-A-n-ndd!! You're going to water-cool . . . . well, maybe . . . . maybe . . .

Since you have so much stuff to play with that a contemperary gammer would find antique,
i can understand why the need to protect a hard modded board or an old one that the original coating has krazed on.

ASIDE: I've used a very brittel laquer called stress coat. That when dry, the full mechanical load is applied and the coating will crack in a pattern, indicating the areas of flex

Go here look for protective coatings. This is much more than the stuff at SVC but the products are a known and they do have a forum on tips 'n such.
Trying to be of service..this is not a neff Sorry, look for circuit sealer.
