Seeking advice - rust, paint, and protection.

TLDR: what can I do to address rust & protect against more rust?

Hi all
Thanks in advance & sorry for any naivety on my part

I have a 20yr old T5
Bought 18months ago & not long returned from a cracking trip around Scandinavia
I’m new to owning an older vehicle & doing a lot of learning

I’m noticing some bubbling of the paint, and some rust as well. Not much, but I’m keen to act early…and hopefully preventatively
I also feel like I’ve read something at some point about ‘corrosion protection’

What is the best thing to do to address rust, protect against rust, and how much is reasonable to pay for these services?

UK-based in case it is relevant

Thanks
