Can this be repaired?

I bought this lens before few weeks here (today I got it) and the only one I can blame for this issue is the customs (I sent a complaint). Nevertheless, it's SMC-A 35-105 f3.5 and I can berely put a cap.
Can this, somehow, be repared?

Send an email with the pictures or the link to Eric. He does a ton of lens repair work and he would know if it is even possible and will provide an estimate.

Bent filter rings happen quite often and there is a tool specifically made to repair it.

I use wood scraps to make a form that fits the outside of the filter ring, with the curve it's supposed to have, and a long piece with the inside curve on one end. Then I can push or tap the dent out. I usually have to reshape the inside piece a few times as it gets damaged. Wood won't cause any more damage to the filter threads. I keep going until a filter fits again.

Whatever you use, patience is best. The lens doesn't need any more shock damage.

That's an awesome looking tool. $50 is worth it to have around in case of a drop, but would also pay for itself in buying 2 lenses with dented rings...

Fixed!

Well, I didn't have to order tool for $50. All I needed is little bit of searching and then I found this:
Now, lens is fixed and this are the pictures of my way of doing it with tools that are quite primitive (in design) compared with those on yt video.

Kind regards.

Edit: Most important, with using wood, the metal threads stays intact!

Well, due to fall (on the floor?) in the customs office (or some place like that), I noticed that A 35-105 has the focus to infinity problem: 0.5mm before it reaches the end is the focus to infinity; after that it's little bit blurry. It doesn't bothers me that much but little devil inside of me is telling me that I need to have that feel: when it reaches the end that I know it's focus to infinity.

What do you think?

That is common for many lenses, especially zooms because temperature can affect it. Better to go to far than not far enough. I don't have the 35-105, but 0.5mm sounds acceptable to me.
