Siggs Tank Restoration < 5 L

The perfect solution for anyone who wants to get rid of rust in their tank once and for all: With the Siggnature Tank Sealing Service for tanks up to 5 liters in volume, you’re getting a professional service from one of the most renowned moped repair shops in the scene. This isn’t a DIY fix—it’s a clean, proven process with long-lasting results.

This offer is for anyone who wants to have their moped tank professionally reconditioned—whether as part of a restoration, a rebuild, or to preserve its value over the long term. Suitable for individual tanks with a capacity of up to 5 liters.

At Siggnature, the tank is completely derusted mechanically, ensuring that even stubborn deposits and pockets of rust are reliably removed. 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 tank that’s ready for reliable operation.

Especially with older mopeds, rust in the tank is one of the most common causes of carburetor problems and rough engine running. With this tank sealing service, you’ll create a clean, long-lasting foundation and enjoy long-term peace of mind from rust, dirt, and deposits.

Service Process: You can follow the exact process in Sigg’s video. Additionally, 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.
