I did nothing special to the MDF before I installed it. I just wiped it down with a damp cloth to remove any dust particles before installing it.
1 mil = .001", so this vinyl is about .01" thick.
OK ... based on what I read here, I ordered a roll of this stuff to "see for myself". I put a CP together last night and used this to cover it up. I must say it came out pretty nice, but here are a couple of notes for those of you that might be considering it.
1. Make sure your surface is COMPLETELY clean and flat before applying this vinyl. Any particles that you may have left or any imperfections in your wood underneath will show up very clearly. This stuff is not an option for you if you are trying to "cover up" a woodworking mistake or imperfection in your wood.
2. This stuff is very very very sticky once you peel the backing off ... not like contact paper where you can lift it up and place it down again. Be very careful when you apply it to your wood. If you make a mistake like bubbling or folding of the vinyl, you WILL have to start over.
3. This stuff is very easy to cut with a razor (or exacto knife) making it very easy to work around edges, cut out holes for trackball, etc.
All in All ... this is pretty good stuff. It looks very professional when finished and the price is pretty good considering you should be able to cover 2 pretty good sized CP's with one roll.
Thanks for the tip, OSCAR.
