Many gear heads may cringe at the thought of using car body fillers, due to their massive overuse and destructive impact on the classic car restoration industry. But if used correctly car body fillers can be a fantastic tool to even out areas on a body panel and prevent rust. So, read on below for a simple step by step guide to using car body filler today!
Step one – Prep the surface
Usie a scotch-brite pad to scuff the surface of the primed metal, this ensures that the body filler will adhere properly to the surface. Once the area is primed, make sure to blow away any sanding dust to ensure the area is clean and ready for the car body filler to be applied.
Step two – Measure the amount of filler you’ll need
Though there’s no way of accurately measuring how much filler you’ll need by using a piece of spring steel and lining it up against your car body, you can clearly identify the size of the area which will need to be filled to bring the area even with the rest of the car panel’s surface. If you use too much filler you’ll end up giving yourself more work to do later, so getting an estimated measurement is a good idea.
Step three – Add the hardener to your filler
Now that you’ve got a fairly accurate idea of how much car body filler you’ll need, you need to add a small amount of hardener to it. Again, there is no exact amount of hardener that you should add, but by checking the product guidelines you should be able to establish an idea of how much hardener you need to add to the filler. Ensure you mix both the filler and hardener together thoroughly until you have a uniform colour across the mix.
Step four – Apply the car body filler
Using a plastic squeegee, apply your mix of filler and hardener to the area of the car that needs it and use your piece of spring steel from earlier to even out the surface removing any excess car body filler.
Step five – Drying
Now it’s time to let the filler harden, its best to let the car sit in the sun, but if that’s not possible then a dry garage space will suffice. While the area dries, if you have any other dents that need fixing then this is the perfect time to start the process again to fix them. It usually takes around 10-15 minutes for the filler to cure fully.
Step six – Sanding and checking
Now that the car body filler has cured, you need to smooth the area down again ready for painting. But as you sand down the area, you may notice some darker coloured areas. These darker spots are where low spots in the surface still exist. If this is the case, then the process will need to be repeated until there are no longer any dark spots visible. Once done and sanded smooth, you are ready to apply the paint and make your car look as good as new again.
