Hi

I agree with Whitewolf on the tape as it is easier to use but I found it does not take paint well though so it depends on what you want it to look like.

As for the mesh, this is the stuff I bought. Will do at least a couple of tanks possible more if you are careful with the cutting.

Hope this helps.
