It is better to use special chemical paint removers that do not affect the structure of the metal, or contact a professional.

If you see signs of welding, grinding, or unnatural dents in the frame rail area, this may indicate that the frame has been replaced or rebuilt after a serious impact. In such cases authenticity of the number is questioned and an examination will be required.

⚠️ Attention: If the number on the side member is completely unreadable due to corrosion, vehicle registration may require a forensic auto inspection to confirm its authenticity.
