Do stop-leak additives need heat and/or pressure to work?
I have a somewhat unconventional (surprise!) solar panel setup - a 4' x 20' extruded plastic pool heater feeding a set of glazed copper panels. Works great, but over time (and with deer walking on the plastic pool heater) I get a couple of pinhole leaks each year. I've been fixing them with plastic epoxy, but it doesn't really bond well and it's a PITA.
Would boiler (or radiator) stop-leak work in this setup? It's not pressurized except by gravity (maybe 5psi at most) and the lower parts of the panel don't see very high temperatures - typically 120
or less. The small passages in the pool heater portion are perhaps 1/8" diameter. The panels use water - not glycol.
I think some additives have small particles and some are pure liquid, but I really don't know much about them. Any help, wisdom, or insights are appreciated as always.
