Does anyone have any strong opinions on this radiator stop leak products? Do you know of any that work without producing clogging or overheating, etc?
This issue has been discussed endlessly on the forums at Jag-Lovers.org since Jaguar owner's manuals called for putting Barr's Leak (various spellings are around) in the aluminum block V12. Most forum members have decided it's a terrible thing to do because of buildup of gunk in the cooling system clogging radiators etc. At some point I looked in the Owners manual of my Buick Park Ave and found that GM also calls for it. Somewhere I read it is because there are unavoidable casting flaws in aluminum that make it a good idea. Doesn't make sense to me, so I probably am not remembering this very well. I never use it.

It will fill holes for a while as long as you keep the pressure off. Unfortunately it like the other stop leak products is not selective. My opinion is get the real problem fixed.
That's because it's nonsensical as stated. The correct statement is as follows: There are casting flaws in *poorly-designed and/or poorly-made* aluminum castings. I've owned many vehicles with aluminum blocks and/or heads, and none of them needed Clogg's-Leaks in order to remain leak-free. But then, neither of them was made by GM (known for doing things in a cheap and shoddy fashion) or Jaguar (known for doing things in a British fashion, which is effectively the same thing).
