Cleaner Overview:

The Pacer Technology Zap® After Run 2 Engine Cleaner and Corrosion Inhibitor is a concentrated formula designed to dissolve existing corrosion, restore electrical conductivity, and protect engine components and electrical connections from corrosion-related issues.

About the Engine Cleaner & Corrosion Inhibitor


Versatile Corrosion Protection

This high-tech corrosion inhibitor penetrates existing corrosion layers to restore conductivity across electrical connections and helps protect internal engine parts during storage. In the model railroad community, it is used to keep tracks clean and connections consistent by helping eliminate arcing and sparking that can affect layout integrity. The product also supports storage protection for small engines by allowing a small amount to be added to cylinders, while metal parts, tools, bike chains, cables, and other components can be treated to help prevent corrosion. Its chemical action allows hard-to-reach contacts and surfaces to be treated without relying on mechanical cleaning.

Features:

  • Dissolves existing corrosion from connections
  • Restores electrical conductivity to connections
  • Protects engine parts during storage periods
  • Does not damage plastic components
  • Keeps model railroad tracks clean
  • Helps eliminate arching and sparking issues
  • Treats hard-to-reach electrical contacts easily
  • Prevents corrosion on stored metal parts

Includes:

  • (1) 1oz Zap® After Run 2 Engine Cleaner & Corrosion Inhibitor

Great product. Excellent service from Amain. Thanks

Matt PerserVerified owneron Pacer Technology Zap® After Run 2 Engine Cleaner & Corrosion Inhibitor (1oz)

The best after-run I've ever used, and I've used them all, most are just wd-40 in a fancy bottle, this one is thick and goopy, seems to increase compression and engines treated with it never seize up.

this is the best After Run Oil you can ever buy , it will protect your engine very well.

What reviewers say

Reviews are mixed. Three of four reviewers rate the Zap After Run 2 five out of five, praising its protection against corrosion and seizing, its thick consistency, and a reviewer's perception that it helps compression. One verified owner rates it one out of five, reporting varnish buildup and a seized engine after storage, though this reviewer compares the product to a different engine's history and the account is anecdotal. One review also praises the seller's service rather than the product itself. The reviews do not include independent testing, so claims about compression and seizure prevention rest on individual experience.

  • + Protects engine from corrosion
  • + Thick, goopy consistency
  • + Prevents seizing for some users
  • + Perceived compression improvement
  • − Reported varnish buildup in one engine
  • − Reported seizure after two months of storage
