Best Car Body Filler UK

Regardless of how careful you are with your car, it is inevitable that it will get scratches and potentially dents at some point. When that happens, and a dent puller isn’t an option, a good car body filler can make it look brand-new and smooth again quickly. These fillers fill in those dents and dings so that you can sand them over and then start on your paint job on an even surface. Most fillers are made out of some type of putty and are super easy to work with, even for people who have never done this type of job in the past.

Best of all, most car body fillers are very inexpensive, and a little bit of the product should go a long way with the right purchase. Most companies put their product in either a small tin or a large tub. In both of these cases, you’ll get enough to accommodate more jobs than you might think. Check out our recommended 5 top fillers for car bodies below for sorting out any unevenness without having to replace a panel fully.

Automotive Body Fillers Buying Considerations

Made From

They are usually made out of materials such as resin and fibreglass. What the body filler is made from isn’t too much of an issue, it’s more what material the chosen filler is designed to work with.

Material Compatibility

When you’re looking for the right filler, it’s important to make sure that the product you’re researching can handle the material you intend to work on, whether that is steel or metal, wood, concrete, or even plastic. Most body fillers can accommodate more than just vehicles so even if you need something to repair a model aeroplane or an old guitar, you can do so easily, inexpensively, and with great results.

Spreader Provided

Some purchases come with a spreader to help get your filler into all the areas you want on the vehicles body, though saying that, most of them provided aren’t really of any quality at all, so buying one although it might be an extra cost, might be the right solution in most cases.

Ease of Spreading

You can have the right spreader for getting your filler all over the body of the car, but if your chosen filler sets too quickly, then it’s going to make spreading about the body of the vehicle very difficult and challenging. You want one that doesn’t set too quickly, but still hardens and fills in the gaps properly.

Final Word

Car body fillers are inexpensive yet incredibly effective when you’re trying to get rid of dents, scratches, and rust stains on your car or truck. There’s no doubt that you can keep your vehicle a lot longer and save yourself alot of money in the long run with regular care and maintenance. A good tin of body filler can cost very little and can be considered an investment as it can save you having to replace or repair a car body panel.
