On my 2002 LS430 I have a spot that looks a little hazed , sort of semi cloudy,
What is the best polish to use for this?

You might want to ask in the detailing section. You would probably get more help there and from some of the pro's.

Where is the haze? Hood, trunk, door? Maybe a pic or two will help.

Generally speaking, you want to use the least aggressive method to achieve your desired level of correction. Without knowing the type or level of the paint defect, I'll say the following:

Lexus paint is known to be soft, so you don't need an aggressive polish or pad to achieve the same results as an Audi or BMW, for example.

For light defects:
Two-step process: Menzerna M105 with a white pad, followed up with M205 with a black pad.
One-step process: Menzerna PO203S with a white pad.

For heavier defects:
Two-step: M105 with orange pad, then M205 with white pad.
1.5-step: PO83 with orange pad, then remove polish haze with PO106FA with grey pad.

For ease of correction, use a random orbital machine polisher such as the Porter Cable 7424XP. If you want to try advanced correction techniques, try a Makita 9227C rotary polisher.

Use smaller pads if you are correcting a small or tight area, larger pads for larger areas.

The first thing you need to do is to get good understanding of the underlying problem affecting the clear coat. What made it haze up? Has the surface of the clear coat been mechanically scuffed/scratched or was it damaged by some chemical and it the damage on the surface - if so it can be corrected with appropriate compounds and careful polishing. Just be careful as already posted and try the mildest polish first - burning thru the clear coat in attempting to fix a defect is a common and very costly error. If you don;t have experience in this it might be better to take it to a good detail shop. The LS is the wrong car to learn how to polish and correct paint defects.

If the problem goes through the clear coat or is originating under the clear coat then its more serious and cannot be diy repaired.

The only thing anyone can polish and wax on a modern car is the thin transparent layer of clear coat which is applied as a continuous top coat over the pigmented paint. So its a two layer system (three if you count primer).

If the clear coat has been worn or scratched completely through, or if its deteriorated to a point where it cannot be polished out, then usually the permanent long term fix is to sand, and repaint the affected section of the car and then reapply clear coat.
