Product Details


This ESF Formulation of our Rustbuster Techshield underbody wax is adjusted with a flow control additive that allows an excellent spray film of under body rust proofing wax to be applied. ESF Formulation can be spray applied via our Cordless 18v kit or our 240 kit.


Product description


Black Satin waxy film dry to the touch after a few days depending on temperature.


Flexible self healing film.


Can be applied over existing paint system or over Rustbuster Fe-123 Rust converter.


We recommend a two coat application is best.

First application as a lighter tack coat sprayed over the whole area, Leave this for the solvents to flash off around 1 hour before applying a second full coat.


Clean up is with white spirit.


Rustbuster Techshield ESF Under body wax will not adversely effect underbody rubber or plastics, however we do recommend masking the Brakes and brakes hoses before spray application.


Top Tips

All test data has been carried out at 20 degrees c. ESF Under body wax will spray best when warmed to this temperature or higher. In cold winter months you will need to store the wax at room temperatures or heat prior to using in your electrically operated spray gun.


ESF Formulation Under body wax is NOT designed for injection into hidden cavities via a 360 degree fine spray injection tip. Injection should only be carried out with the Rustbuster Techshield High Performance formula.


Supplied in 1 ltr , 2.5 ltr or 5 ltr easily decantable tins.
