Possible hylomar replacement

Possible hylomar replacement
VersaChem gasket sealant type 2 and 3
http://www.versachem.com/catalog.aspx?catID=2
Seems similar to hylomar and alot less expensive. Any experiences?
I know hylomar is still available, but it's like $30 a tube and it becomes semi-hard very quickly unlike the old permatex hylomar. We use the versachem type 2 at work and it acts just like the old hylomar.

I coat my coolant o-rings in hylomar to help them seal and to hold them in place.
I actually put a thin layer of ultra black rtv on the housing interface as per a tip from a major builder.
We use at work for a regular gasket dressing. I never see rotaries in there unfortunately...

a major engine builder told me to not use hylomar on the coolant orings and advised me to use crisco to hold them down. worked great for me. also used it to hold in the dowel orings, front cover oring.. and all the hard seals. crisco is easier to work with, cheaper, and cleans up quick

Did he say why not to use hylomar? It's one of the intended uses of the product. I can't say the same for crisco...
Atkins Rotary, Kevin Landers, and myself use it with great results.

crisco is just vegetable oil. its inert as far as i know. if it was petroleum based i wouldn't wanna eat any baked goods lol.
he mentioned that hylomar just wasn't good bc it was hard to work with.. getting it cleaned off the face of the iron housings takes a lot more time. crisco is harmless if it isn't all wiped up, hylomar can gunk things up/interfere with the mating of housing surfaces. he saw no benefit of using hylomar, and the best part is that that a can of crisco is like $3 for 1lb of the stuff at any grocery store.. and it comes in butter flavor

Crisco and pet jelly are oil based. Most rubbers have a low resistance to oil based substances.
I understand that the FSM recommends petroleum jelly, but I don't agree with that recommendation. After pulling apart motors that used pet jelly to hold the rings in, I noticed that the o-rings were swollen, had changed dimensions, and felt softer. Pulling apart engines assembled with ultra black and hylomar yielded o-rings that looked, measured and felt brand new after thousands of miles.
Hylomar can't interfere with the mating surfaces because it remains pliable. All but what is left filling imperfections is squeezed out. Messy? Wah... My pressure washer removes it with ease when cleaning engine parts. Get a new hobby/job if you're afraid to get your hands dirty.
Preventing oil seepage between the mating surfaces? That's the only use? I don't know what that is referring to. I'm not aware of any oil seepage problem, since the coolant o-rings seal coolant and combustion pressure and the only oil passage that has pressurized oil around there is isolated by o-rings and is on the outer part of the cooling jacket.
Look guys, this isn't an argument. Plenty of people use hylomar.
I wanted to know if anyone has used versachem in it's place, not your feelings on the use of kitchen items in an engine.

Although Permatex no longer sells the Hylomar HPF, you can get the same stuff from Valco, you need to order the solvent free Hylomar, the valco hylomar you most often see is the medium blue, which starts out like jelly and turns into paste. Part numbers for the solvent free are:
71300 HYLOMAR, SOLVENT-FREE, 12 oz. cartridge
71301 HYLOMAR, SOLVENT FREE, 3.5 oz. tube & nozzle in box
71316 HYLOMAR, SOLVENT-FREE, 8 oz. brush-top can
This is the same exact stuff Permatex was selling as thier Hylomar HPF.

I'm still interested in the versachem stuff since it's rated to 425 deg F (almost as high as hylomar) and is inexpensive in comparison.

That Valco stuff hardens too fast, and it makes nice little ***** all over the place.
The Permatex HPF does not harden as fast, and it's "workable" for almost an hour.
I'd take the Permatex HPF stuff over the new Valco stuff ANYDAY.
In fact, I was asking around if anyone had any stocked away?!??!

My girlfriend found Hylomar for me at Harbor Freight of all places!
It is "Hylomar Pit Lane Product, universal blue, racing formula.
It goes on super thin and then hardens up at a good pace to do coolant seals.
She went back and bought every tube they had once she confirmed it wasn't "gaylomar" (what she calls the Valco stuff that hardens instantly in our climate and only sticks to itself).

loctite no3 aviation compound , non set for the timing cover gasket, will not fully harden and block the OMP passage
petroleum jelly/ vaseline for OEM water seals and for oil passage O rings
thin smear of red RTV high temp silicon for the housing legs
( housing interface around the "legs" of the housing to sump )
and also a THIN smear of RTV to hold non OEM rounded water seals chord for assembly
( viton or nitrile chord , fused up with iso -cyanate )
the RTV works fine on the housing legs if torqued up while non set

Loctite 518
Remarkably similar to the original Hylomar.

Is that the stuff in the green tube? I saw that on their website and thought it might be like the permatex stuff because I noticed the universal blue has a heavy solvent odor.
I'm still interested in the versachem stuff since it's rated to 425 deg F (almost as high as hylomar) and is inexpensive in comparison.

Yes, it comes in green packaging.

You are confusing the Hylomar Universal that Valco sells with what I listed. Universal is crap, but is what most vendors stock.
Here is a listing of the different hylomars from the source:

Read what they say about the advanced formula (solvent free)

A good friend and A&E introduced me to Hylomar in 1972 when we were experiencing blowby around the cylinder studs on our Bultaco engines. He brought me a 4 oz. tube of Hylomar in a yellow tube and the label indicated that it was manufactured by Rolls Royce to Continental Aircraft specs. Unfortunately, after 20 years, what was left in the tube had dried up. That 4 oz tube cosi me $6 and was well worth it.
Has anyone visited the local airport to try to source this?
