054 Developer
After 30mins the penetrator was removed from the area of the suspected crack. As you can see even after drying off what I could see I still managed to miss a loft of it. The Developer the white chemical was then spray on. This reacts with any remains of the penetrator and will high light any cracks in the block. As you can see by all the penetrator I failed to clean off the developer has worked and there is NO CRACK!...
