Rustbusters Frequently Asked Questions ( FAQ’s )

Q. How do I kill rust?

  1. Rust is a natural process, it can be stopped by not letting the steel come in contact with air and water? The quality of the chosen treatments and barrier coatings is critical to your success in treating rust

Q. Why should I pay more for Epoxy-Mastic when I could use an ordinary paint to the same effect.

  1. Rustbuster Epoxy-Mastic can be applied to a rusted pitted surface with outstanding results. True even an ordinary Dulux type of gloss will provide a barrier against air and water for a period of time but it would require routine maintenance and will not withstand salt water stone chipping and engine oil and petrol and should not be applied to anything but a suitably prepared surface. Epoxy-Mastic will do all this and more. It’s very small molecules flow into every pit on the steels surface before linking and chemically curing to an exceptionally strong penetrating flexible coating that will last for years.

Q. How do I treat rot.

  1. You cut it out. Rotten steel cannot be treated.

Q. Should I apply fe-123 converter before the Epoxy-Mastic.

  1. fe-123 is a converter for the treatment of rust (ferrous oxide) fe-123 will convert ferrous oxide (rust) to iron tannate, bound in a latex binder. Fe-123 needs to be applied to rust to work. If you have prepared your steel with a powered wire brush you will have removed most of the surface rust and in this case you should use the Epoxy-Mastic, applied direct to the pitted steel. However where you have badly pitted steel or hidden seams it would be beneficial to use the Fe-123 followed by the Epoxy-Mastic, if in doubt please ask first.

Q. So why use the fe-123 converter.

  1. Sometimes it is not possible to see the rust in hidden cavities or seams on these occasions the fe-123 is the only thing that will work well. Or you may want to convert the rust and paint it with conventional products not the Epoxy-Mastic, in this case fe-123 makes an excellent base to start from. But remember “fe-123 should be applied to a rusted surface or a power tool cleaned surface where rust may still be present within pits in the steel.” fe-123 is also recommended prior to the application of a cavity wax if you know hidden rust is present. If you are in doubt please ask first.

Q. Can Epoxy-Mastic be painted over

  1. Yes you can paint Epoxy-Mastic with single or two pack paints.

Q. Can I apply Epoxy-Mastic over an existing paint coating.

  1. Yes you can Epoxy-Mastics very low solvent content means that it will not react with other paints.

Q. How do I apply Epoxy-Mastic

  1. By brush roller or spray

Q. Do I need to wear special air fed breathing equipment to spray Epoxy-Mastic.

  1. No you only require a cartridge filter respirator suitable for paint fumes exactly the same as used when spraying any other paint.

Q. Do you have a wax injection diagram for every vehicle.

  1. We have hundreds of injection diagrams these are readily available to our customers when they purchase sufficient Dinitrol products to complete the job. Not all manufacturers would have commissioned a drawing so in these cases a drawing will not be available. We have drawing archives going back to the 1950’s please ask and we will do all we can to trace a diagram for your vehicle ( this service is unavailable to those not purchasing products from Rustbuster Ltd )

Q. Can I get a Warranty from Rustbuster Ltd

We guarantee all of our products against defects, we will always uphold your statutory rights.

We can offer a warranty on vehicles we rust proof as well they will need to be either 3 years old or less or a brand new restoration.

The first step is to book your car in for a rust proofing appointment, on careful examination of your vehicle we will be able to tell you if we are able to offer an anti corrosion warranty. This may include the replacement of certain parts before we are prepared to put the vehicle into warranty. If you vehicle passes and the required repairs have been carried out along with the rust proofing you vehicle will be in a warranty to either replace or repair any future corrosion on structural parts of your vehicle, floor sills sub frames etc. To continue the warranty the vehicle will have to visit Rustbuster every year on the anniversary month of its rust proofing for an annual service and top up. Any years missed and the vehicle immediately falls out of warranty. Please call to discuss this further. The regular rust proofing service may be of interest to you if your car is older

  1. How often should my car be rust proofed

Your car should be inspected annually to repair any damage to your rust proofing, every five years the vehicle should be re-injected and any dry underbody protection replaced.

  1. How often if it has been rust proofed by Rustbuster

If we have rust proofed your car on our regular Hot Fog rust proofing service for say £500 we would invite you to book your car in for an annual service at a cost of £60 + vat we will keep the car in tip top condition as long as it is returned to us every year.

If you do not return to us for an annual service we will Rust proof the vehicle for the same rust proofing charge as originally charged plus any increases to the price list. The Techshield underbody wax has a life to service of 5 years. Obviously if you had returned the car every year for its service then on the fifth year you would only have paid £240 for those extra 4 years. It is much cheaper, less than half the price if you bring back your car every year for a rust proofing top up service.

  1. Where do I take my car for top up service or warranty work

We will only undertake work service repair or warranty repairs at our Spalding premises, if you have anything at all you are not happy with them all work will have to be carried out at our Spalding premises without exception.
