Is Permatex threadlocker any good?

Went to three auto parts stores this morning looking to get some blue Loctite for my cam & cam retainer bolts. Well, no one seems to stock the stuff anymore. All they have is Permatex. To make matters worse I'd forgotten my glasses, so I couldn't read the fine print on the back describing the applications. What I could tell was they seemed to have a pretty low listed temperature rating.

Is there a good Permatex to use on internal engine fasteners? Or should I continue to search for some Loctite?

Go to their web site, click catalog, click threadlockers, and click loctite blue.
when the description comes up, just below that it has "WHERE TO BUY'.
A short form entering your address and city it will give you the nearest location to get it. www.loctiteproducts.com if you really want it.
Hope this helps.

You want blue for the cam bolts. The blue is a "serviceable" type meaning you can remove them if needed. The red is high strength meaning it can be removed but requires the use of heat from a torch to break the bond. The green is a "wicking" type. There are no fasteners in an engine that should require anything other than the blue except maybe if you were installing head or main studs, then you may want to use red for those. Any threadlocker requires that the threads be well cleaned and primed with the appropiate cleaner & primer.

I myself have used the red locktite for three different cam swaps on my cam bolts and was able to get the bolts loose without putting heat to it. I just put the socket wrench on it and loosend it up. The stuff does work good from what I have read. I never had used blue or green. I would use read for any really critical bolts like cam bolts etc.

No, and I'd use the red again when you go back together,
