Putty Basic Type

I used to swear by Squadron green putty - until the last tube I bought, and I couldn't get rid of the pinholes, even after several applications! After buying a tube of this stuff, no more pinhole problems, finer grain, sticks well to plastic, wet sands easily (I never dry-sand on plastic). Caution: Will probably mar the plastic finish if you get it where you don't want it, but that's what makes it stick so well.

This is a basic gray putty that fills well and stays in place. This dries fast, and any excess can be easily cut away with a hobby knife. It sands pretty well, but only if it has dried. If you try to sand it before it dries completely it will make a mess. This should be used with putty application tools to get the best results. A tube of this is not small, and should last through many models.

Great all around filler. Dries fast and sands easily. Only complaint is that it will shrink when filling larger areas so two coats may be necessary. But all in all good stuff. One tube last forever.
