The household and plumbers goop doesn't have corrosive properties because I have used it for seven years now and I just puled some chassis mounted caps out of the mc240 I did six years ago and the stuff peels right off and shows no signs corrosion.

standard silicone caulk is corrosive. No need to take my word for it. A simple web search will provide all the answers needed. They do make acetic free silicone and that is fine.
Did find this in a MSDS sheet for plumbers goob. It would make me think twice for film caps. Maybe you didn't read it?
Not recommended for use on polystyrene, polyethylene, polypropylene, Styrofoam™ or paper products, and any items that come into contact with food, drinking water or animals.
There is a reason why they make an electronics grade silcone adhesive. Why not us the correct product for its intended useage? Penny wise and pound foolish?
...the incompatibility with plastics takes two forms. In one form, the solvents in it attack polystyrene and similar materials like styrofoam by softening and dissolving them. The other form of incompatibility is that the stuff simply doesn't stick to some plastics like polyethylene and polypropylene because these materials are fairly inert and quite resistant to the solvents.
Personally, I don't use the stuff because I find the smell nauseating. Also, if I can't devise a mechanical of means of attaching a new part, I don't use it.

Thanks for the info.I only use it because I rebuild a lot of vintage gear with exotic modern caps and I don't want to drill and cut the units up because they will kill the vintage value..This stuffs holds really well but with a quick twist you can also remove it with no traces whatsoever..On kit amps where they have preexisting holes such as in the citations or Eicos or Heathkits,I use the clamps in that situation.

Thats possible..Its a form of silicon but its safe and thats why a little tube is five bucks.
