You can also accomplish this task with 80-grit sandpaper and a wire brush, but the job gets much harder. If you can’t reach easily, use a wire brush or hand scraper to remove all dirt and rust.

  • Repairing with Glass Fiber Gel

Glass fiber gel strongly repairs the surface. Mix the glass gel and the hardener, then press the mixture into the damaged area. After 15 minutes, it starts to get hard, and after almost an hour, you can sand the surface.

  • Sanding the Extra Glass Fiber

If there is extra fiber gel pushed out from the rust holes, use Ronix angle grinder and the flapper wheel for sanding it off. The hole surface should be a little recessed so that you can fill it with smooth body filler.

  • Applying Body Filler

Mix your body filler with a suitable amount of hardener, then use a flat spreader to press the mixture of filler and hardener into the holes on the rusted surface. Try to flatten the hole surface as much as possible so that you sand it less later. Remember to apply enough filler to avoid leaving any spots, scratches, and pinholes on the body surface.

  • Sanding the Body Smoothly

This step is the most time and energy-consuming step of bodywork since you should sand the body surface before painting it. Start with Ronix orbital sander and sand off any excess body filler. If the body filler isn’t too hard, the sander sands it fast, but in case it’s hardened, you need to put more effort into sanding it. You can also use 400-grit sandpaper or a sanding block to make sure you don’t face a wavy surface finally.

  • Cleaning the Job Area

Use the tack rag and mineral spirits to remove and clean dirt or grimes since any fingerprints, specs of oil, and dust cause spots. So, cleanliness is highly important from this step on.

  • Applying primer

Spray a thin coating of primer over the entire area. Repeat this step again and again for some minutes to make a slightly thicker coating, and then let it dry.

  • Wet Sanding

The primed area needs to be wet, sanded, and feathered, then wipe it clean and allow it to dry; finally, spray another layer of primer on it. Use 600-grit sandpaper, a higher grade one or the Ronix branded orbital sander at the end of this step.

  • Spraying the Base Coat

Use a base coat (the color paint) and cover it with a protective layer of topcoat (the colorless paint); you can also spray two or three layers of paint without the topcoat. Spr ay two or three thin coatings of paint over the primer coating, repaired area, and original paint.

  • Rubbing Out and Polishing the Paint

Take advantage of Ronix electric polisher to rub and polish the paint layer; this helps you get a glossy finish. Start with wet sanding, spray another layer of paint and polish it to achieve full gloss. Congrats, you are done!
