RTV Vacuum Chamber: Headspace vs Shot Size | RUUIPON
Size the vacuum pot to the mixed cup, not the pump. Foam rise needs headspace. Overflow, weak pull, and when a bigger chamber still fails. MOQ 20, $50 CAD.

Winter Shop Temperature vs RTV Cure Time | RUUIPON
A cold bench thickens platinum, stretches pot life, and fakes inhibition. Heat the rubber and the room, not the logo with a torch. Typical shop. MOQ 20.
