Let’s start with the heavy duty grits and what they’re used for.
32 and 40 grit sandpaper can be used for sanding and grinding paint down to metal. It will allow you to cut out old body filler or shape new filler if you have some extremely high areas in your bodywork.
32 and 40 grit sandpaper can also be used for sanding heavy rusted areas and cleaning them down to shiny metal. Then you can proceed to treat the rust and move on to repair and refinishing.
80 grit sandpaper is the most common for shaping body filler. It’s a great grit to cut and shape your body filler and sand down rusted body panels. I find myself using 80 grit during the rough draft stage when doing major body work. It’s a great grit to use that will help you lay the foundation to move toward the finer grits that I talk about below.
If you chose spray a primer sealer over that, you may, but is not needed to get a pro finish. I actually show you theses steps on video in step-by-step format inside of the VIP members area. Check it out here and get full access to save yourself a whole lot of time and money. [ Ссылка ]
BASECOAT CLEARCOAT SYSTEM FINAL PAINT GRITS:
In the end. You want to finish your final sanding when prepping for basecoat clearcoat with a 400 grit sandpaper. This is the BEST grit to paint over. Don’t listen to what others are saying all over the internet. Follow those who are doing it and getting professional results. I have been painting for over 18 years and have a lot of knowledge when it comes to auto body. John Kosmoski and I don’t agree on every method when it comes to auto body, but when it comes to final paint grits, we agree that 400 is the best grit. Why? It gives you enough paint TOOTH for your paint to grab on to. If you sand any finer, look forward to some paint peeling in a few years. 600 grit is on the fence and at the border. If you feel that you just NEED to sand finer, I would absolutely not sand any finer than a 600 grit paper. We paint pros recommend 400.
SINGLE STAGE PAINT SYSTEM FINAL SAND PAPER GRITS:
Simply slap a 280 grit paper on your DA (dual action sander), and you’re off to the races. As I said, you can safely paint over a 240-280 grit paper when painting single stage. But personally, I like to get it a little smother. If I’m painting a single stage job, I get the paint prep down to at least a 320 grit finish. Check out the 24 hour El-Cheapo paint job that I did that came out fantastic. I did it under a tent outside using a single stage enamel system and I documented the whole process on video for you right here in the VIP members area. [ Ссылка ]
REFINISHING SAND PAPER GRITS:
Most common grits are: 1200, 1500, 2000, 2500 and 3000.
These sandpaper grits are used for detailing and refinishing like color sanding and buffing, or maybe you’ve heard the term cut and buff. This process is done to take out common paint finish issues such as orange peel, runs or dry spots in your clear coat. You can also rejuvenate older paint jobs by color sanding and buffing your paint.
Don’t worry. I’ll show you this exact process in step-by-step video and detail so you TOTALLY get it. To learn more about how to see all of this on video so you can repeat the process in full confidence, see what you get inside of LABAP VIP here. I know you’ll be amazed.
When you have your clear coat all sanded down and finished with 2000-2500, you’re ready for buffing. I’ll cover buffing, pads and compounds in another lesson.
I’ll see you in the next lesson!
