Hey everyone,

First time going to be refinishing any firearm and looking for advice. My dad has a TC Renagade from the early to mid 80s I believe. I was going to by a build your own kit but inquired about his Renagade since I know he doesn't hunt with it anymore and he gladly dug it out and gave it to me. He always takes fantastic care of his firearms but to his horror the outside of the barrel had a huge rust spot on the outside of the barrel. Its been in his case for years and thinks something obviously wasn't completely dry in it. Inside of the barrel is spotless though.
I want to take everything apart, refinish the stock and most likely blue the barrel, especially with this rust damage. I have the feeling that getting it off is going to really scuff the barrel.

Thanks to internet and youtube, I kinda think i know how to sand down the stock for new stain. One question is, do I need stripper for this to get started or just start with straight sandpaper right off the bat?

Suggestions on how to tackle rust on barrel? Im reading WD-40 and a brass brush?

What can i do with the other metal parts like trigger guards, hammer etc? Just reblue? Ive read about cold blue but do i just put that over whats on the metal and barrel now or do I have to remove what is currently on it somehow?

Product recommendations would be helpful as far as type of brush to remove finish, stain type, best barrel blue etc. Thanks and as soon as i get started i'll keep a thread going to hopefully help other beginners such as myself. Thanks!
