I have used the same and similar adhesives over the years and the trick I have used is to place a piece of wax paper on top of one surface, lay the fabricate on top and get it aligned, the slide the paper out as you press the fabric down onto the dash or similar hard surface. The flatter the surface the better this works but at least it helps eliminate the possibility of wrinkles, etc and having to start over. Learned this technique from a kitchen counter top builder who glued formica sheets to the underlayment.
