Layout/lead dress question

[Pine]

Is it bad to have the cans of your power supply filter caps touch one another? I added some in parallel to my existing caps to change the value, and due to space considerations, they are lying on top of the original caps. I haven't noticed anything out of sorts but I would like to run it by you guys before I finalize things. Thanks in advance.

They almost always touch so I can't see it being a problem.

If any two caps are wired in serise you stand a chance of the top caps( top of stack)plastic insulation case getting nicked and having a short. Dielectric fish paper need to be use to reduce that chance.
