Plastic Cement vs Super Glue

Plastic cement welds styrene parts together. CA glue bonds almost anything, including resin and metal, but does not melt plastic.

Choose Plastic cement if

  • You assemble standard plastic kits
  • You want strong seams
  • You need a little adjustment time

Choose CA super glue if

  • You attach photo-etch or resin parts
  • You need instant grab
  • You fill small gaps

The bottom line

Keep both: thin plastic cement for main assembly and CA glue for small and mixed-material parts. Use canopy glue for clear parts.
