These write up are for your information only and may not be complete.  I tried these projects out my first time also, my way of doing thing may not be the best way, if you have any suggestion for improvement, let me know.

Use them at your own risk.
If you need more help, email me. I'll try my best to help.

Questions from donated visitors will have my highest attention
Send me a request if you interested to see how something is done. If time permitted, I will create a DIY project based on your request.

Why pay someone when you can do it yourself?

If you want to do it right, do it yourself, because no one cares about your car more than you.
