Slides move too easily

I've never had this problem, but here I am.

I recently acquired a mid-70's Olds fiberglass sousaphone that had been sitting in someone's attic for multiple years. First thing I did was take it to the shop to have the slides unstuck and get the pads and corks replaced. They did a great job.

However, now my slides, especially the main tuning slide move too easily. The main slide is right under my right arm when I'm playing and if I bump it at all it slides all the way back in. It seems like even from the factory these slides weren't tightly fit.

Suggestions on what I can do about this?

A really thick slide grease might be a a good temporary solution. I think hetmans has a slide grease specifically for loose slides, as do some other companies as well. Might want to look into that.

However, it doesn't look like I can actually buy it anywhere.

I'll try this UltraPure Heavy slide grease. According to Amazon comments, looks like it's suitable for this purpose.

You can have your tech slightly expand the slide so that it moves normally. This is relatively easy to do and very inexpensive.

Automobile owners - often - don't like mechanics' "honest-to-goodness/really-will-fix-the-problem" advice, because those solutions are often costly and involved.
Mostly, automobile owners are hoping for potions (etc.) that can be applied or poured in, or something like a "computer reset".

The same is basically true with instrument owners with problems.
:arrow: Notice how many people on this website put their hopes in this-or-that valve oil as a solution to their valve problems (which are ACTUALLY either lime/dirt problems or valve-wear/valve-damage problems...or - in this case - some sort of "just right" slide grease).
---------------------------------------------------------------
Someone (last week...?? twenty years ago...??) probably buffed the crap out of some of the inside slide tubes, and/or someone expanded the crap out of some outside slide tubes.
The BEST solution (as expanding inside slide tubes for a better fit - as a solution - is always inaccurate and crappy) is to find a junk Olds/Reynolds valveset with good/not-ruined tubes, and swap out tubes (insides only, or pairs - if both are ruined) that are the loose ones.
