Hi, I'm at the wet sanding portion of my restoration. I have three coats of Motobase metallic base coat, and five coats of ********** Universal Clear. I'm sanding with a 3/32 orbit DA, and 3M Trizact 1500 pads as my first step. It's working really well, but I don't want to keep going until I consult you knowledgeable folks. This is my first time doing this, do I sand until all the orange peel is gone, or just until it's knocked down? Obviously I don't want to remove too much, but like I say I'm new. I'm attaching pictures of how it currently looks after working on it for a while. Keep going?
How much do I wet sand?

My opinion, with 5 coats of clear...keep going til its flat.

Yep, no shiny spots. I recently tried using the DA with 1500 and 2000 film discs but dry sanding. Much easier to tell when its flat but be sure to wear a dust mask. Are you using an interface pad like the 3M 05777 Hookit 6 Inch Soft Interface Pad? 1968 Coronet R/T

Thanks. I am using the 3M interface pad. I just want to make sure I'm not sanding off too much. I should leave corners and edges along though, right? |

I try to remove orange peel right up to the edges but you have to be very careful doing so. Make sure the DA rotation is going "off" the edge and not "into" the edge. Going into the edge it has a tendency to grab the edge and burn through. It is the same when buffing.

'68 Coronet R/T, I'm done with 1500, no orange peel left. It's easy to see when the 1500 step is done (no orange peel), but what about 3000? So far I've done my hood with 3000 and it is definitely shinier, but slightly hazy. Is this what I want? How can I tell how much to sand with 3000? |

Ive been wet sanding my 64 Fairlane here lately and Ive sort of developed a feel and sound to know when Im done. Ive started judging it like clay barring paint to get it ready for wax. When you've sanded with 1500 and move to 2000, keep sanding until it sounds like you arent cutting anything anymore and the resistance againt the new grit is gone.

1500 to 3000 is too big of a jump IMHO. I rarely ever need to sand beyond 2000 grit. Megs 105 and a twisted wool pad on a rotary will clean those right up. 1968 Coronet R/T

You need 2000.

I very rarely wetsand above 1500. I like wetsanding by hand, btw. Because it's easier to keep it uniform and get to the edges.
Even after 1500 sand, going straight to a wool pad with meguiar's diamond cut doesn't take too long to buff out nice. If using m105 ultra cut it's even faster. If you do wanna sand more, go with 2000. All it does is makes buffing a little easier. 3000 accomplishes literally nothing, unless you're going to be hand polishing afterwards. It's nice for small corners or edges where a buffer can't reach well. |
