GLISS-COAT ® describes a range of dry lubricant coatings developed by Aalberts surface treatment. While these functional anti-friction coatings reduce friction and wear, they also avoid squeaking and creaking noises. Once applied, most of the GLISS-COAT ® coatings are matte dark gray or black. When pressurized, they take on a shiny appearance and …

Use a glue stick. Sometimes just one letter is a problem. It might be that just one of the ends of a script letter won't stay down, or another delicate piece isn't sticking well. An easy solution for this is using a simple glue stick. Just put a little bit of glue on the back of the letters and restick them.
