Siggs Tank Restoration: Frame Tank

The premium solution for anyone who wants to permanently remove rust from their frame tank and ensure it’s technically sound: With the Siggnature Frame Tank Sealing Service, you get a professional service from one of the most renowned moped repair shops in the scene. This isn’t a standard process, but rather meticulous handwork requiring specialized knowledge and experience.

This offer is aimed at anyone who wants to have a frame tank professionally reconditioned—whether as part of a restoration, a rebuild, or to ensure long-term operational reliability. Due to their design and accessibility, sealing frame tanks is significantly more labor-intensive than sealing separate tanks.

At Siggnature, the frame tank is completely derusted using mechanical methods. This involves the use of special fixtures and clamping systems that allow the tank to be rotated in a controlled manner and ensure that all interior surfaces are reliably treated. This is followed by phosphating to ensure optimal surface preparation and provide long-lasting rust protection. The tank is then coated on the inside with a high-quality sealant in multiple passes. The result is a permanently protected, rust-free frame tank that is ready for reliable operation.

Rust problems are particularly critical with frame tanks, as they are often difficult to detect but can have massive effects on the entire fuel system. With this sealant, you create a clean, long-lasting foundation and gain long-term peace of mind against rust, dirt, and deposits.

Service Process: You can follow the exact process in the video by Sigg himself. In addition, your package includes a detailed step-by-step guide straight from the workshop to take home with you.

Notes: Once the tank has been sealed, powder coating must not be performed, as the heat generated during the process can damage the seal inside.

An awesome custom product straight from the Siggnature workshop.
