Max H,

Thanks for that tip. I was needing to tough up the firewall on one of my planes and was going to make a trip to the hobby store today for some black paint and a small brush. Then I saw your post, it did the trick and did not cost me a dime (nor gas) and it works. Just another way of saying that you do not have to spend a lot of money in this hobby.

That is why I come to RCU. People have great ideas and are willing to share. I would not have even thought of using a magic marker (too simple I guess).

Thanks again...
