If you are looking for a thicker material to fill certain gaps, then why not make your own.
Take a bottle of Solvent Weld about 1/4 full, and then break up small pieces of model sprue and place it into the bottle with the solvent. Push the brush cap back and seal the bottle. Leave it for a day, and all the sprue will have melted into the solvent. If its still a bit runny, then add more sprue and let it brew again.
This material will take a while to dry, so only use it for gap filling if you aren't in a hurry.
