For this you’re going to need some adavanced skills and tools. car detailing Melbourne First off you’re going to need some specialized sandpaper. Now it’s personal preference on weather you want to use a sanding block or a powersander. For this I used a sanding block. You’ll need at least 1000 1500 and 2500 grit paper. Some go to 3000 for final feathering. You’ll also need a Rotary polisher pads and product.
As you can see the scratch is quite long and deep. Normally I wouldn’t have touched this because in most cases it really is beyond what most detail shops would go through. Something this size would usually call for a repaint on the panel which of course can get really expensive. But I’ll walk you though it and show just how it can be done for pennies on the dollar providing you have the right equipment and skills.
Now the first thing you need to do is fill the scratch in. Your local Auto part store or dealership will have the matching paint. You can use body filler if the scratch is really deep or just layer up the touch up paint. But the point of this step is the complete filling in of the scratch. (this is where a lot of people tend to leave it and why touch up paint always looks horrid)
After you layer it up nice and thick and the scratch is 100% filled in and completely dried (drying times vary on the paint used) you can start the wet sanding process getting the paint down nice and smooth. I used 1000 grit 1200 grit and then 2500 grit for final feathering. This can take some time to get right. Paitence is always key. This is a very delecate step. Take your time go slow and check progress often. You don’t want to sand to deep or through the paint. No need to be aggressive eventually it will all become nice and smooth
Next up. Double check the work and once it’s all set up and nice and smooth. And there’s no hint of the scratch remaining start to polish it up. First you’ll need a compound to get the wetsand marks out. After that step, you’ll switch over to a nice polish and finish up with a great coat of wax. Now the key here is to use high quality products. You really don’t want run of the mill polishes and compounds that have a bunch of fillers in them. Because once the fillers evaporate out the scratches from the wetsanding will show right back up like a lightbulb… Always choose quality.
And voila! the scratch has been removed. With a little practice this should be easily acheivable. I demostrated this on what would be considered a Major scratch that should be left to the body shops. I did this to show just how far it can be taken if needed. The smaller the scratch obviously the easier the correction on it. Of course the location of the scratch will always play a key role to in this process. It’s has to be located in an area that can be corrected. Crevices and seams are much more difficult to achieve the proper results.
