About Us

Your car’s changed a lot over the last century, but we’ve still got the solutions to your problems. Douglas Holt first started developing products to keep his own car running, and 100 years later we’re still working hard to keep your car on the road, getting rid of those clunks, leaks and squeaks. During the war, Douglas Holt spent time working for Austin Motor Company where he learnt about motor cars and mechanics. After the war, keen to use his knowledge and earn his own money, he opened a small shop selling car parts.

Early cars experienced many problems as people got used to the technology. Many cars suffered cracked cylinder heads due to people not using anti-freeze, leading to leaks. To solve this problem, Douglas Holt launched Wondarweld to allow people to seal leaks in their cars easily. Wondarweld is still sold today. Holt continued to innovate, and new products were created thanks to problems with his own car. Gun Gum was one such product, invented after Holt’s own exhaust needed repairing. Gun Gum is one of Holts’ most successful products, still available today.

1990 saw the launch of Bradex, another solution to a frustrating problem for drivers. Bradex is used when your car won’t start, to get you on the road. This useful product is still available today as Bradex Easy Start. In 2018 we launched our Headlight Restoration Kit, a quick and easy to use kit which removes scratches and oxidation for clearer, brighter headlights.

    I used this for scuff marks and deep scratches on my car bumper – it’s the perfect stuff for small wounds. Just put a small blob on the enclosed spreader and spread it on!
    It’s ready mixed the tube and dries within minutes – you realistically only have half a minute to work it so not really useful for large areas but thee waiting time between applying and sanding to a fine finish is just a few minutes so it is very quick and easy to use.
    And so cheap! The days of spending loads on a tub of two-part fillers and wasting most of it have gone – this stuff is highly recommended

    Easy to use, it is really a cream colour compared and applied to the scratches on my white car, have yet to sand it down ready for painting as on my car paint is required to get the correct colour but like it is at the moment is much better than seeing the black plastic of the bumper.

    Bought tp fill two holes stupidly drilled in the tailgate of my car (to fit number plate) by the selling garage who should have know better. Appears to have worked well.

    Works well. It goes off in seconds, so the secret is be prepared and don’t try to do too much at once.
    Get the prep right before you use it and you’ll have no problem.
    It is quite thick but that is useful when you are working on vertical panels.

    This stuff is good but it has a very short working time from when it’s squeezed out of the tube. You need to do small areas at a time and try and spread it out as much as possible

    I used this product probably 50 years ago, and it was just as good then as it is now. Don’t know how long I’ll live to say about durability! Easy to use.

    Golden Review Award: 4 From Our UsersI used to use Holts cataloy to repair my old cars in my youth so brought back some fond memories!
    This time it was bought to repair our Grandson’s resin gnome which had suffered an unexpected, gravity driven, visit to the patio floor. Holts to the rescue! I used it to fill in the gaps after gluing the main pieces together. A lick of paint and Eric the Gnome was restored to full ‘elf’

    5.0 out of 5 stars Classic solution!

    This turned out to be quite sticky or gummy compared to what I was expecting- dries very quickly however and sands to a smooth finish just fine. Make sure you use gloves though.

    I found this easy to put on, dried quickly. Definitely not for bigger areas. Easy to sand. Paint covered really well. Would recommend for small chips as per label. Not for rust repairs

    Golden Review Award: 11 From Our UsersI bought this knifing putty to level the surface on my Moto Guzzi California’s paintwork, after some rust spots had been removed and then treated with anti-rust. The putty applies and adheres well and drys reasonably quickly. Once dry and set, the putty is easily sanded to a smooth finish, ready for application of undercoat/paint.
    For the small amount of rust I was treating, there is still loads of this putty left, so as long as it’s shelf life is good, it will be even better value for money.

    Used on white metal model cars (1-76 scale) gap filler. Put it on quickly as it dries fast, sanded down next day with wet&dry course grade and 600 grade for smoothing off. should work with real car bodies but don’t hang about, will spray undercoat later.
