Advice on paint defects
Polishing - Marks
Very fine lines in the paint surface with a low gloss greyish appearance from polishing paste and/or cloth.
- The sensitivity of the paint surface to polishing marks is greater when: the paint has not been allowed to dry for long enough; the film thickness is too high; the incorrect choice or amount of hardener has been used.
- Excessive pressure has been exerted on the polishing machine, (polish burnt in).
- Polishing machine tilted during polishing process.
- Wrong polishing head.
- Aggressive/coarse polishing paste.
- Polishing when the painted surface is too hot from the oven or in direct sun light.
How to avoid
- Ensure only the correct film thickness, drying times and choice of hardener and thinner are observed. Before polishing, allow the paint layers to dry sufficiently (rebake using Infra Red if necessary).
- Do not press too hard or tilt the polishing head and use the correct head for the application being carried out.
- Do not use too coarse a polishing paste. 6] Ensure that the paint surface is cool and/or not in the sun.
Polish out the problem with any standard deep gloss polish. If the problem is more severe, first use Glasurit Fine Polishing Paste 562-1602.
