This is the 2nd plant. Both were repotted at a nursery. Using the correct planting soil we water when it's dry and don't over water. This plant was full and healthy looking, then all of a sudden it goes straggly and many branches appears to die. Some remaining branches look bad towards the bottom, but new growth on the ends. We do the correct light and have treated it for bugs with Neem oil from the nursery.
I need a little more information. Is the pot it is in well-draining? Is it indoors/outdoors? What bugs did you treat your plant for? What kind of lighting is it receiving?
In the meantime, I recommend reviewing the information in the following article to ensure the panda plant's needs are being met:

My husband left my plants outside on our patio, and I live in Texas where it's real hot in the summer, and now my succulent is dried up from standing in the very hot sun. How can I help my plant get back? One of the flowers already broke off the stem.
Your plant can be moved outdoors in the spring and summer but that hottest sun of the day is probably to much for it!
I would trim away the damaged portion of the plant.
Just give the stressed plant some recovery time in a shaded location.

White patches on leaves as if paint were splashed on it. Destroys the "fuzz" underneath it. Patches start out small and get bigger approx. 1/4 inch in diameter (irregular). Help!
This could be a leaf spot fungus. Keep a good air flow around the plant and avoid water splashing on the leaves.
An application of a fungicide can help.

My panda plant has Mark's on it like this in different varieties, this is a picture is after 2xs of being washed with rubbing alcohol. I put meed oil on it today. The 2 other plants it was by has nothing wrong with them at all. Can you please help, this stuff doesn't wipe off, it will scratch off but I'm not willing to hurt my plant like that. If more pictures are needed let me know I'll send more.
It looks like a pest, such as mealybug. You are on the right track with the treatments. They are hard to get rid of and take several applications.

This is all over my panda plant. This picture is after it's been cleaned 2 times with rubbing alcohol. I now have meed oil on it. There is no change to the plant and no other plant it has been near has any problems.
