I thought that i would share my thoughts and experience with the relatively new product parking bay "SPACE MARKERS".Over the years i have been looking for a solution to marking parking bays in "not the normal surface areas" ie:- Shingle,Grass,Base Type 1,Gravel.After using Space Markers from Product Markings i have had great feedback from our customers on how impressed they were with the end results.So simple yet very effective was the reply's we had from all our clients, which include Main dealer car/van distributors,Holiday/Residential parks,Theme parks,Restaurants, So if you are like i was at first not sure about this product, definitely give them a go i am a small road/car park marking business that now uses them whenever i get the need for marking difficult surfaces with great results and happy customers.
