RB 3 Blocker Assortment by Motor Guard Review

I just couldn't warm to them. They are well made of aluminum and I think the design is ok. But after using them, I still prefer a piece of wood or a plastic tube, something you can easily adapt to your immediate running needs.

As a painter/body detailer I can say they are a must have. You will see the difference between them and the (old) colored pencil. Less likely to cut edges or cut into corners, and shape blocks are great for round shapes and concave pockets. I wish I could say I don't use them on a daily basis, but they see a lot of action.

Whilst this product is very well made and will do the intended job for which it was designed use caution when sanding with water as these blocks are encased in heavy aluminum If they slip out of your hands when wet, they can chip and/or scratch the paintwork. I think it would be better if the material used is some composite or some other kind of non-metallic substance.
