Let's start by saying that nothing and nobody can totally prevent untreated steel from rusting! But treating steel can help to prevent rust. So I have invested in new equipment to treat your Bongo or Freda and help to keep rust away.

Why does a steel vehicle rust?

Rust is formed when steel and oxygen react with water or mositure in the air. Surface rust is flaky and permeable to moisture. Beneath this surface rust, more moisture and oxygen make contact with steel. And it continues to corrode. Given sufficient time, your steel Bongo will completely rust away. Waxoyl rust treatment provides a barrier between the steel, air and moisture.

How long does it last?

By undersealing your Mazda Bongo or Ford Freda, I can start to prevent the worst damage that rust can do.

If undersealing treatment is reapplied to your Bongo at intervals, it can continue to help to protect your vehicle from corrosion. The re-application inteval is generally every 3-5 years. This varies, depending on weather conditions and vehicle use.



How do we underseal a Mazda Bongo or Ford Freda? 

First, I clean the Bongo's underside to see the rust clearly.

I use high pressure sprays to remove flaking rust.

Your Bongo is dried. 

(Some Bongos require more preparation than others! Some also need welding and panels or sills replaced.)

I seal areas (such as breather vents) that should not be treated with waxoyl.

I apply Waxoyl (wax oil) rust prevention treatments under pressure.

The Waxoyl treatments can be injected into body panels. This is applied with high pressure, as a mist, so penetrates further.

How long does it take?

Your Bongo or Freda is best left with me for at least one full working day, and then overnight. 

If this is not possible, you can collect your Bongo as late as possible, on the same day.

What does it cost?

Not everybody wants, or can afford, a high-cost treatment.

So my treatment options are tailored to suit your budget.

I can underseal just the underbody, or the underbody including wheel arches and under bonnet, or the under body, wheel arches, under bonnet  with injection into panel cavities.

This starts from £175+vat.

If you fancy undersealing your Bongo yourself, I found a video that shows you the general idea: WAXOYL APPLICATION GUIDE I advise you to wear protective clothing and a mask designed for this work. 

Rust and corrosion on a Mazda Bongo

These are a few photos of rust on an untreated Mazda Bongo.

As you can see, it had never been undersealed.

It came in for an MOT and failed on 'excessive corrosion' in several places.

It took a me a couple of days of cutting and grinding to remove the rusted parts and weld replacement panels and repair patches. Once it was restored to good condition, I undersealed it to help to keep it that way!

Needless to say, the Bongo then passed its MOT.
