Tailgate letters-adhesive type

I have a Red Tacoma with chrome bumpers. I would like to fill in the TACOMA letters. I think either the black or chrome would look good. How do the letters adhere? If it's peel off backing , is it hard to get them all aligned to the edges first try? I have read about some using soapy water solution which allows some fine tuning of placement. How does that adhesive work? The water evaporates and the adhesive still sticks? Does those letters have peel off backing or is it activated by water? Thanks. Any pics of chrome lettering with chrome bumper trim would be appreciated. Leaning toward black to match black bumper step trim

Thanks a bunch. Looks like the soapy water methods really helps get them aligned.
