❓ Essential Q&A
Yes, but only on surfaces sealed with clear coat or hard paints. Always test first as aggressive polishing may damage thin paint layers.
Very long! You only need tiny amounts per application. One tube typically lasts for many models with regular use.
For professional results, yes! Coarse removes scratches, Fine smooths the surface, and Finish creates the mirror effect.
Stop immediately and clean the area. Over-polishing can damage details or overheat plastic. Always use light pressure.

Which glue should I use for plastic, resin or metal?
Plastic cement welds polystyrene kits; resin and metal don't react to cement, so use super glue (CA). PVA is for basing materials only.
Green Stuff or Milliput — which putty?
Green Stuff stays slightly flexible and holds fine sculpted detail; Milliput cures rock-hard and sands smooth, ideal for gap filling. Many modellers mix the two.
How long does epoxy putty take to cure?
Workable for roughly 60–90 minutes, fully cured in about 24 hours at room temperature — check each product's description for exact times.
