Silicon Caulking and Wood Lacquer

[Alenpowa]

Hi everyone, I hope you guys can help out, first of all, I want to say that I don't have much woodworking experience and I'm sorry if I will be asking noob questions.
I'm from Italy and I'm currently trying to make a vacuum forming machine, the problem is that in the youtube video this guy uses something he calls wood lacquer and silicone caulking, I have no idea what kind of material he uses and I really hope somebody can tell me more about what materials I will need to buy.
Here's the wood lacquer he uses:

And this is the silicon caulking:

I have been trying to ask in the video but he didn't reply and as well he didn't share any amazon link.

I really hope you guys can help.

Thanks

Hi, thank you so much for the reply.
I'm trying to make sure to get the right material.
Here's a silicone that is used for kitchen or bathroom projects, it's a sealant silicone, it's not made for wood, do you think that would work?

About the lacquer I read in the description of the one you sent me that it's used to fills the pores, I know that in Italy there is something called pores filler, do you think is it the right one?
Tura pori means literally pores filler, it's a water-based product.

Another option I found available to buy is a varnish.

Honesty I have no idea which one is best, I really appreciate your help!
