For aerospace cryogenic applications or installations requiring sub-zero performance below -40°F, 3M 427 may be the better choice. For everything else — adhesion strength, foil thickness, and value — AF-30A is the stronger specification.\u003c\/p\u003e\n\u003ch3\u003eSurface Preparation \u0026amp; Storage\u003c\/h3\u003e\n\u003cp\u003eSurface must be clean, dry, and free of dust, grease, oil, and condensation before application.
