Body rework and rebuilding are common tasks in body shops. Identifying the scope of damage to select the right product is key. In this how to, we show you an innovative rebuilding method for non-structural metal car parts. It is suitable for application where you might have used traditional tin soldering before.
See our TEROSON® EP 5020 TR in action.
TEROSON® EP 5020 TR is a lead- and tin-free alternative to tin soldering and is ideal for rebuilding of car body metal surfaces. It is excellent for grinding and the removal of interior parts is not necessary if welding is not required—no open flame used. Try it out for yourself!
All repair and maintenance tasks shown should only be done by professionals. Please do not try this at home if you are not qualified or professionally educated. Always follow car manufacturer's instructions.
Limitation of liability
Grind and rebuild the surface mechanically (e.g. dent remover/hammer).
Clean and pretreat repair area with TEROSON® VR 10 and a lint-free cloth.
Open the TEROSON® EP 5020 TR cartridge and squeeze out a small amount of material until both adhesive components run equally. Apply the mixing nozzle and discard the first 5 cm of the adhesive.
Apply TEROSON® EP 5020 TR to the rebuilt area in a way that the area is sufficiently filled with excessive material (between 3 and max. 5mm). Keep the nozzle tip inside the material to avoid air inclusion.
TEROSON® EP 5020 TR is sandable after ~2.5 hours at 23°C. Warm cure at 60 °C object temperature for 15 minutes is recommended to accelerate curing by infrared heater. Do not use a hot air gun for heating.
Sand the material with P150 paper to achieve a smooth surface contour and rebuild original shape.
Remove abrasive dust with a lint free cloth soaked with TEROSON® VR 10.
Before applying bodyfiller, apply BONDERITE® M-NT 1455 W to bare metal as a corrosion protection before applying bodyfiller.
The use of bodyfiller e.g TEROSON® UP 210 is required. Apply and spread TEROSON® UP 210 together with the hardener (ratio: UP 210 golf ball size, hardener pea-sized) to re-shape the rebuild area.
Apply BONDERITE® M-NT 1455 W instead of EP filler for metal conversion and corrosion protection. Only use as a step before paint work.
