Using a liquid/paste type of "Anti-Skweek" compound on '65-'82 Corvette is not really a good idea, tho a lot of folks do it. You really don't want to "glue" the pads to the pistons in these calipers...it increases the likelihood of the pistons pumping air back into the calipers, which is a major issue to start with. It would be better to find some anti-squeal shims to use between the pads and the pistons. I'm sure one of the Corvette brake suppliers(Vette Brakes & Products or Stainless Steel Brakes) would have them, if the local parts house doesn't. I've never used them on a Corvette, so I couldn't say for sure if they work as well as they do on "normal" cars.
If the pads are squealing, there is a problem with either the pad material, or the surface finish of the rotors.
Were the rotors turned when the brakes were done originally?
What type/compound pads are you using? Organic, semi-metallic, ceramic, etc?
A brake squeal is basically just a vibration. Loose fasteners can cause it, as can pads that are loose in the caliper, or pads that have not had the proper high temp grease used on the sliding areas between the pads and the caliper guides.
IF the pads are severely glazed, you can help remedy this by removing the pads, and lightly sanding longways on them with some 80 grit paper. Another trick that I use is to cut(I use a hacksaw) angled grooves in the pads, at about a 45 degree angle, angled front to rear, and cut about 1/2 the pad thickness. About 3 grooves per pad is usually enough to accomplish the mission, which is to give the gasses created when using the brakes a place to escape, as well as giving the brake dust created a place to escape, instead of building up on the pad and rotor surfaces. You can also grind/file a small bevel on both the leading and trailing edges of the pads. Most new pads already have this feature, but not all do. This gives the pads a "soft" corner on the rotors, instead of a flat, cutting edge.
