Welcome. Being new to the site, you need to be sure to read the "Read Me' posts at the beginning of each forum. The ones here for example recommend that you just post a general introduction here and post tech questions in the appropriate tech forum, maybe Body- Exterior in this case. This will give you the best chance for a good answer.
Also, general questions like this have been covered in great depth on the board already. Be sure to use the search link in the menu above before posting a question to avoid duplication.
