For the wet sanding process, here’s the sandpaper. We’re going to be using we’re going to be going from 1500 to 2000 to 3000 to 5000 grit

These are very fine sand papers, so we’re going to start out with our 1500 grit sandpaper.

It’s wet. it’s been soaking in soapy water for about ten minutes and grab a sponge and wrap the sponge in the sandpaper.

What the sponge is gonna do is when you’re apply pressure, It’s going to even out the pressure and it’s also going to conform with the curves of the car.

So let’s start the wet sanding. The first thing i want to do is spray down the entire area with soapy water. Get it as wet as you can and also make sure your sandpaper is wet also.

You want to stand back and forth not in circular motions. We are going to want to come up into the factory clear coat so that we could have a nice smooth transition from factory clear coat to brand new clear coat

and while you sand, you don’t want to focus in one spot, you want to use long strokes and move along the entire body of the car.

Once you’re done sanding, spray the area down with soapy water and then clean the area with a microfiber towel .

so with our 1500 grit wet sand completely done now

We’re gonna go and move to the 2,000 grit.

so spray the area down with soapy water, sand the entire panel smooth and clean it off with a towel

After our 2000 grit, we have a nice uniform haze. You could kind of see the new paint in the old paint but once we buff that it’s going to come right out. It’s gonna look so good.

I cannot wait to finish this so let’s go and wet sand with the 3000 grit sandpaper following the exact same process as we’ve been doing then dry it with your towel

and finish up with the 5000 grit using the same exact process and finally clean the area off and let it dry completely so after our 5000 grit

Let’s remove the tape and we’re onto the last step

And that is to use a Polish to bring back the shine in this paint and you can do this by hand but I highly recommend using an electric buffer like the following because this is going to make your job so much easier.

And you’re really going to get a great shine out of the paintwork

so all you have to do is put a little polish on the wool pad and hand buff it into the paint work until it’s spread out then use the buffer on a low setting keeping it under 1,200 rpms .

Keep that buffer moving, so you don’t burn into the clear coat and you don’t have to press hard, let the buffer do all the work for you

After you’re done buffing, wipe down the panel to remove the polish and check out this shine. This came out awesome.

I’m by no means a professional painter or a professional bodywork guy but the whole point of this series is to show you what you could do at home

So this gives you a good idea of the results you could expect if you were to take this on.
