redacting without using the redacting tool

I asked this question a few minutes ago and had a reply, but I could not reply to the comment, so I need to start again.

Here is my original question:

I don't want to use the redaction tool to block text.

I selected the comment tool (looks like a square talking bubble), then selected the shape boxes, then rectangle.  Then I outlined the text to create the rectangle around it.  I wanted it filled with grey so did that, same with the border.  So this blocked out the selected text with grey.  Now I want to write on top of this "redacted" with white.  How do I do this?  I have tried adding another rectangle, a text box, just clicking the large "T", and can't get any text to happen.

The answerer said I needed to use the redaction tool or else it could easily be removed.  I should have gone on to say that after I redact the way I want to and not with the redacting tool, I will print out the page, and then photocopy the page.  So the redaction cannot be removed.

Please answer the original question be answer now.
