Couple of problems I need help with..

[oasis100]

1. There are 2 holes in the resonator, maybe .5x.5 inches. I heard about a product called MAGIC PAINT from **************s.com. Has anyone experienced using this product to cover up rust spots?

2. The low beam/high beam lights are not turning on, but the fog lights can turn on. On the dash, the high beam light is on when i switch to the low beam. Would a burn light bulb take out the entire low and high beam lights?

3. When I turn the steering wheel in a large degree there is a squel noise, what could it be?

thanks for any help.
