(54) Corrosion protection apparatus


(57) An apparatus for protecting a substrate includes a collapsible reservoir filled with a three-dimensional elastic gel which is relatively soft and has an ulti­mate elongation of at elast 200%. The apparatus is disposed in contact with a substrate having a recess therein to be environmentally protected, and a force is applied to the reservoir to at least partially collapse the reservoir forcing the gel from an open surface of the reservior into the recess so as to substantially fill and encapsulate the recess.
