| |
The Escape : |
| |
Scrape out Orange peel and repaint. |

| |
| 6). Sags and runs |
| |

|
| |
The Verdict: |
| |
Undercoat and topcoat of paint should have identical physical properties. Allow drying time between two coats. |
|
| |
The Escape : |
| |
Entire coat must be completely removed. Exposed base should be then rubbed down to a smooth face and primed before repainting.. |
| |
 |
| |
