Have you ever had sand or ballast get all messed up when you tried to wet it before gluing, I hate it when that happens.  My wife got this bottle for doing hair stuff and I love how fine of and soft of a mist this puts out.  If you pull the trigger just a little you get a quick fog, if you hold it down it goes for a much longer time without having to keep pumping it.  also, it works at any angle without running out, even upside down!

I've been experimenting with the American Model Builders peel and stick shingles. Specifically set #285 3-tab shingles. I like the appearance of this product, they adhere well and take coloring very well. My problem has been with removing the backing from the shingles. I've been using a knife blade to try to find the separation plane for each strip of shingles. Sometimes I find it and sometimes I get a spot that is 2 plies of the paper. Once I get it started it's no problem. Does the group have any advice on starting a peel?

My existing scenery is a variety of fine and coarse ground foam over dirt, all held in place with diluted matte medium.  I am wanting to largely convert to using static grass.  I'm wondering if 1. I can apply the static grass over the existing ground foam, 2. need to pick off the large pieces of ground foam, or 3. need to scrape off all the ground foam before applying the static grass using an applicator.  Any suggestions as to the best approach?

In my opinion, vehicles can make or break a scene.  This is the first time I have modeled anything close to the modern era since I have been modeling 1915 for the past 15 years, so I literally know about nothing when it comes to trucks and trailers.  I am building a model of Thurmont's NVR homes for my Maryland Midland RR and thanks to Google Earth I can see that there are a number of tractor trailers on the site.
