i dont know i think next time if i spring for mylar im gunna apply it like window tint except use 3m spray adhesive on the wall. any one ever tint a window??? this is my plan in about 4mos ill post some pics
my idea was to spray an even layer down with the 3m, tape the piece im working with to the celing and spray the side i would be lookin at with an excess of soapy water then squeege and credit card the fuck outta it till it was smooth against the wall sould be easy enuff to wipe down to clean after the glue cured but i sure as hell dont know about removing it though maybe peal it off clean the wall and repaint sure as hell wouldnt be a quick process but patchen vent holes aint either
