JT, what "el cheapo block seal treatment" product did you
use?

I have a friend with a 99 Civic with intermittent
overheating and intermittent loss of coolant. The level
seems to go up at times like Tegger said. Can't see any
bubbles in the reservoir. No suspect residue is on the spark
plugs or oil filler cap. (Plugs in fact look beautiful.)
Can't smell anti-freeze in the exhaust. But I also can't see
how it could be anything else. Been several weeks of the
overheating/loss of coolant problem. Pep Boys and dealer
have both looked at it and found nothing but likely did not
do a coolant pressure test; cylinder compression test; or
test for hydrocarbons in the coolant.

Her car overheated about three years ago when relatives were
driving it; a rock was said to have hit the radiator; they
didn't know it and so didn't pull over (yeah, I know...
slobs) before the temperature gage hit red. I figure a
breach began about then but hadn't manifested itself until
this particularly hot year hit.

I hesitate to send her to a block sealant product, since
rumor has it they often gunk up cooling systems bad. Told
her at this point best bet is to let a radiator shop
troubleshoot it. But I'll study the packaging of the product
you used and google on it and see if it seems worth a try.
