I have started training again!

After weeks of short runs and walks due to my vein surgery I am finally upping my mileage for my October half Marathon. However I am experiencing the same old problem, what you see above is chaffing and I get it every where, it doesn't hurt, MUCH, but it doesn't look good. I have tried

changing to seamless everything, running in biking shorts that go to the knee, applying anti-chaffing cremes, and using plain old petroleum jelly, but nothing works, anyone got any ideas, before I have perminant chaffing scars?
