 Prevention

- Thoroughly clean the parts using a mild detergent
- Clean the substrate before and after every manipulation
- Use correct plastic cleaner
- Plastic parts should be heated to 60°C to force out any residual contaminants (Make sure that the panel will not lose its shape due to the heat)
- Apply plastic primer according to technical data sheet
- Control if plastic is paintable
