Reddit reviews Testors Plastic Cement Liquid 1 Oz

Citadel's glues are absolutely terrible. I like testor's plastic cement it comes with a brush on the cap to make application easier, and it's thin so you don't get too much on your figures

1. For me I generally just prime and then paint. You can get away with sanding and then painting, but I reserve that for smaller surface areas and for pieces that are going to be painted in a darker or similar color to the original plastic.
   
   
2. You just add thinner to a portion of your paint to make it more dilute and in turn saving paint. It's recommended you take a few drops of your color and thin that instead of thinning your whole pot so the paint doesn't coagulate and "spoil" if you're using a weird thinner (some people don't have this problem, so you can try that out if you want).
   The consistency you want for your thinned paint varies depending on the method of application, but for handpainting, most people thin it to the consistency of water. Not so thin that it's water color-like, but just when it has that watery consistency, that's perfect. I've done this with enamel paints and enamel thinner and the results were great.
   
3. If what you're talking about regarding glue is seamline removal, you do not want to use super glue for this. Use liquid plastic cement like Tamiya or Testors depending on what's available to you. And yes, apply the cement, sand the seam away, and then paint. It makes sense when you think about it; you don't want to sand your paintjob away
   
4. Tip: after you prime, you're not done! Check for any imperfections in the kit like holes or nubs left over from building. You can now sand and fill in those mistakes with putty and then reprime and check again. This is a major step that decides how well your paintjob will turn out.
