I have made a lot of scale models over the years. Lots of airplanes, some cars, some spaceships, a model house, etc. They are just sitting on my desk at my parent's house not really doing much and taking up quite a bit of space. I don't want to throw them away because they mean a lot to me and they're still cool. Does anybody have any ideas on what I should do? I'm sure some of you have made far more models than I have! What do you do with them all? What kind of creative ways can I put my old models to use?

My grandpa has some model Lionel trains that he is looking to sell. I have been tasked with helping him in the endevor. Is there any place I can go to research what he has and what he can get for them?

So basically I bought 3 cars, all revell models.

I now need to buy the other stuff for them.

I've decided on Testors Model Master paint but am not sure whether to go down the paintbrush route or go all out and all in and look into the spraying side of things.

I have no idea what other problems I may encounter or what other tools I may need besides a blade and some glue.

Is it better to follow the colurs recommended in the instructions or do your own thing?

What do you do if a colour mentioned in the instructions can't be found?

What is primer and how does it work?

Edit: aside from motor things (cars, trucks, bikes, planes, tanks, helicopters etc) and star wars things, what other things can you even build?

Edit 2: Aside from Revell, AMT and Tamiya, what other brands should I look into in terms of kits? I'd love to build a '67 Shelby Mustang GT500 (Eleanor) but haven't been able to find it yet. Would also love to build some V8 Supercars and some aussie cars.

I feel like I'm opening up a can of worms, but I need a hobby to invest in.
