Liquid Plastic Cement
This cement is sparingly applied to 2 surfaces of plastic, with a brush or a drop-applicator, and it essentially welds them together, by partially dissolving the plastic; when it has cured, it's almost as if there was only one piece of plastic. I was happily surprised at how well it works, for a product that has been around seemingly ages. In addition to working well, it comes in a safety-capped bottle and provides a brush applicator. It's also a reasonably priced product in the 1 ounce bottle category.
Great bonding liquid cement
I have two favorite liquid cements, and this is one of them. The brush is wider than Tamiya Cement, and the cement is thicker. It is great for wider areas where you want more coverage. It sets quickly, and the bond is strong.
Testors Liquid Plastic Cement
I have just started building models again after a 20 year break. I tried to use the tube glue on the detailed parts on my 1/35 armor models. I ended up getting squeeze out and glue where I did not want it. I remembered using this liquid cement and ordered a bottle. I could not be happier with the results. I am using it almost exclusively on my models now.
