Wd-40 works pretty well
My mg Quanta is good
Looks really good! As for advice. I would say to make the weathering a bit lighter and show through some of the "exposed metal" under the rust/dirt with some grey paint.
I would not get the sazabi ver ka for your first mg because I feel it will ruin your expeirce with most of the other mgs you make after that(you'll expect the same thing from all of your other mgs when it comes to the build).All the ones you listed were good. It really comes down to aesthetics. It would be smart to get a kit that has come out in the past ten years because most of the older ones cannot stand up to the newer ones.
Flouros posted somthing on the dicord a couple of hours ago, if you want to join it I would check that post.
I say go for what design you like most. If you have built 5 hgs I think you build pretty much anything you want.
Well, if its seared then it isn't 100% raw😂
IBO is alternate universe. So you won't have to know any of the big Universal Centuary plot lines to understand it
I feel like it is not even a contest. The avalanche Exia would destroy the lupus rex in space and just has higher specs in general.
I would say the 00 mobile suits on both situations. It seems like the Gundam in 00 are much strager than the normal mobile suits that seem to be around the same power as IBO suits.
Hg or Mg vs Full Mechanics
I'd recommend the rgs if you are comfortable with hgs as well with cutting the peices off the runner to minimize nubs(because of the painted parts). If you have only built hgs so far it might be a little of a challenge, but it probally wont be too difficult.
If your budget is lower I would go for the Crossbone. They seem like they are equally great kits. It just comes down to aesthetics, size, and cost. I would wait for the Nu, but the crossbone on a killer kit.
I would guess IBO. It is one of the more serious shows(though it does have some anime tropes)
If she wants to get into uc then I would stay away from war in the pocket as it has some small spoilers for 0079.
Sazabi of your cool with the price
Yeah, thats what I use
Rg isnt too complex, but you may mess a part or two up. Just have some glue handy
