(Rant) Thermostat Housing Leaks...

Factory, cast alloy aftermarket, stamped steel, billet seen em all, never have leaks as they are all sanded flat on plate of glass, use a gasket and an even thin skim coat of Ultra Black silicone on both sides of gasket. Wrench tightened til good and snug. Only the tiniest beading of silicone ever shows (not mountains of silicone spooged out slathered everywhere) Left to fully cure before any coolant is poured in. Never ever a leak. Still trying to determine what I’m doing wrong. :rofl:
