Cleaning 518

[Jimmy in NC]

For those that go in and out of these cylinders with a gasket delete and use 518 to seal them... how do you clean it off when you go back in? Stuff when cured is pretty stout.

Yes good stuff but a bear to clean. Brake cleaner helps soften it up

I am not sure it will work or not, but try acetone. That is what has to be used for ThreeBond 1194 or 1183.

I've tried both of those...they work but slow.


@Mastermind any ideas?

We used 518 a lot at work. Loctite brand chisel gasket remover worked great. Spray it on and wait 5-15 minutes. Not sure how it will react with mag and aluminum.

I use a razor blade.

What I have been using...making sure I wasn't missing any quick way.

I will look to see if I can find some.

That *s-word'll eat the powder or paint off, has methelene chloride in it. AKA paint stripper.

So be careful how you apply it and wash it off well after the fact.

Same here. Razor blade followed by brake cleaner. Just did it last night as a matter of fact. I do wish there was something easier.

I clean alot of aluminum engine parts at work that are sealed with silicon and anerobic sealer. I knock the big chunks off with a razor and use light pressure with a small fine wire brush. The brushes I get are wooden handled and slightly larger than a toothbrush. It scrapes the sealant off and leaves no marks on the sealing surfaces.
The brush works better than scraping the whole surface for me.

Yes, it is paint stripper

I heard a pro tip last week on gasket removal- dub wheel cleaner.
Safe for aluminum wheels.

Razor blade to get big chunks off. Back drag with a super scraper to get down to clean metal.

I made this video a while ago, it may be of interest here.

The super scraper is AWESOME.

I use one for tough stuff on old AG equipment and the like. A better scraper I've yet to find.

I agree!

Last time I checked they are still made in Cedar Rapids about 20 minutes from me, second generation running the business. I've been to the guys shop to get one warranted, he's got a nice Silvey 510 I tried to get him to part with.

I've been using them since 2000 when I started at the machine shop, like I said I think I bought that one in '02-03.

A little update on this. I pulled my 346 apart today to make a few changes and remembered the discussion about gasket remover. Well... I didn't have any of that but I do have paint stripper. It works pretty damn good. Would've worked even better if I had patience. Lol

You can see it lifting the 518 just like it would paint. I still did a little scraping but it was way easier.

One other thing to note, I use the surface prep spray on the case side. Most if not all of the 518 stays on the cylinder. I don't know if that's good or bad but I've never had any leakage issues.

You will likely never use anything else once you use this stuff, I am hooked, especially made to remove paint from aluminum aircraft bodies,

I simply just use dirko ht instead . Easier to clean up.
