HI, and welcome (back) to the forum!

For now, when all new users make posts, they go to a queue and wait for one of us to mod it in, which is why you didn't see your post show up immediately. So....this one is now in, and I'll delete your duplicate that's still in the queue.

Now that you've posted, use the Google search link in my sig and see if you can find the answers to your cover questions until somebody with some cover experience (not me!!) can come help you out.
