Elimination of minor surface defects (BMW X5 E53)

The deformations of the outer surfaces that have arisen due to minor damage are eliminated by two main methods – punching and straightening, followed by restoration of the paintwork. If it is impossible to use a punch due to the impossibility of access from the back side, then the damage is eliminated by external pulling and the use of polymeric materials.

To eliminate minor defects, proceed as follows: Remove the old paint coating from the damaged area and prepare the surface for painting as described above.

Cover the surface, cleaned to a metallic shine, with a scratch grid, which will ensure maximum adhesion of the putty and the surface being treated.

Prepare the putty depending on the maximum depth of damage:

• polyester putty brand "PE-0089" is used if the depth of damage does not exceed 2.5 mm. Before use, the mass must be mixed with a hardener (100:2.0) and applied with a spatula to a surface cleaned to a metallic shine and degreased;
• epoxy glue based on diane resin type "ED-20" is used if the depth of damage does not exceed 4 mm;
• eP-0020 epoxy putty is used if the damage depth does not exceed 7 mm. Before use, the mass must be mixed with a hardener (100:8.5), then applied with a spatula to a surface cleaned to a metallic shine and degreased.

Apply several thin layers of putty until the surface takes on a shape close to the original with a slight protrusion above it.

Allow the putty to harden to the point where it can be pressed through with a fingernail.

Proceed to prepare the surface for restoration of the paintwork as described above.

The highest quality of repair work is achieved by using polyester putties.
