I'm still open for advise. The dash is out I'm cutting a hole for glovebox.I plan on sandblasting down to bare metal.Want a coating or proces that will last and let the glue for vinyl cover stick.
While asking .What about glove box? I have a molded fiberglass box from EM.It has a flange around it I presume it mates with back of dash pannel.Door came pre covered.Metal pannel covered with black vinyl and a layer of padded vinyl and beading that extends beyond the edges of the metal door pannel,to cover up edges of hole. The hinge looks like it is intended to be clamped between the back of the dash and glovebox flange but is larger than hole in dash so it would have to be slipped inplace through the hole from the front then the glovebox fastened to dash from behind.
I know nothing is forever and I'm a heavey junk mechanic so I bolt and screw everything together I can.The dash is to be covered with padded black vinyl.I don't picture screws showing.I plan on installing a master switch by building a thick washer w/1 1/8" hole center and two threadede 1/4" holes .Bolting through dash into washer locktiteing in place, no visable screws and covering dash and sliding switch through from behind and nutting the two 1/4".The switch can be replaced if necessary and no visable swrews.
I propose the same treatment for glovebox .Bend a piece of 1/8" alluminum strap to follow the flange of glovebox,threading and bolting through dash .Then after the dash is covered I could set the cover inplace from outside and then slide glovebox on screws from behind and nut it place.That way everything is accessable and no screws should be visable through padded vinyl.Am I on the right track or is there a nother way that is much simpler that I've never considered?
