    InformationThe 2-pack matt white finishing polyester putty for car repairs. Easy to use giving a smooth surface after sanding. MPEX Fine Filler has a very good adhesion with various substrates, it can be applied over. Bare steel and aluminium after flatting and degreasing. Zinc coated, galvanized steel after flatting and degreasing. Sanded glass fibre (GFK/GRP), polyester putties, works primers and existing coatings in good condition. Wood substrate after flatting and degreasing. The product is OEM approved and ISO9001 tested.Method of useBefore applying sand, flatten and degrease surfaces. Mix 100 parts of putty to 2 parts hardener and stir thoroughly until achieving homogenous paste. Be careful not to create air inclusions. The hardening time is around 18 - 20 minutes at 20 degrees and this significantly increases if the temperature is below. When sanding the applied area we can recommend P80 - P120 for (dry) coarse sanding and P120 - P240 for (dry) finishing sanding.Useful application information for MPEX Fine Filler
