How to Fix the Surface Damage of an Aluminum Door?

Step # 1: Use Sandpaper to Scrub the Damaged Area

Are there any existing rust or paint marks that have become stubborn and are not coming off your aluminum door? Use sandpaper to scrub the rust & bad paint off. Keep using the sandpaper until your surface becomes smooth to the touch. Your objective should be to remove the lip between the metal & the paint until no rough edges remain. 

Step # 2: Fill the Damaged Area

Once the area is well-scrubbed, use a putty knife to fill the auto body filler putty into the door’s damaged areas. Spread it across the affected area and keep blending until the surrounding parts are even. Now sit back & relax because it will take time for the putty to settle in and cure the damaged area. You may have to wait for a certain period and then start with sanding the patch. 

Step # 3: Sand the Patch Up 

Once the putty is dried, now again, use the sanding paper to smoothen the patch. It will form some fine dust around the frame of the door. To remove the resulting fine dust, use a towel to wipe it. 

Step # 4: Apply the Paint on the Patch 

Lastly, paint the newly formed patch. Use spray paint or paintbrush to paint the batch, depending on your preference. Start with applying a very light coat and check if the door’s coat matches the coat that you have recently added. In case it doesn’t, and it’s too light, then add another layer. Please make sure not to add too much paint, or else it will destroy your aluminum door’s appeal. Keep painting until you get it right. 

So there you go. Here’s everything you need to know about repairing aluminum doors without any hassle.
