Restoring surface structure on bumpers, spoilers and scuff plates.

Restoring surface structure on bumpers, spoilers and scuff plates.


This procedure enables restoring the structure on visible unpainted components after completed welding and grinding. The method can also be used to rectify minor and very superficial damage.

Note

Always use a spray gun with top-mounted cup and a recommended nozzle of 1.8 - 2.4 mm.

An HVLP-system will also give a good result.



1. Grind the damaged area with abrasive paper of grade 400 - 500.


2. Clean the component with Teroson FL cleaner.

3. Mask the component so that only the damaged area is visible.

4. Start by priming the damaged area with two coats of a mixture for surface structuring.

Mixture:

70% Terotex 3000 (white or black)

20% 2K lacquer

Always use 2K lacquer in the mixture to increase durability, even when treating white or black components.

10% Normal hardener (suitable for the lacquer) but not of MS-type.

5. Allow to dry and grind as necessary.

6. “Shower” carefully with the mixture. If a courser structure is required, decrease the spray pressure and spray from a greater distance or increase the spray pressure and spray closer if a finer structure is required.


7. Place the component in a varnishing furnace set to 60°C so that the structure hardens.






Tip: The mixture can also be used to “raise” very small plastic burrs on ground surfaces. Afterwards, harden the component in an oven at 60°C and rub down with Scotchbrite or similar.
