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.
Here’s to another hundred years!
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.
