I know alot of us have had problems/questions in the past wondering which is the best to use so I am going to break it down:
1. aluminum oxide is used by professional coaters (best surface prep)90psi
2. Glass beads 60psi, is also used by the professionals. Why? because mosy places are using chrome base coats and metalic powders are relfective, what give a reflection a polished piece of metal, polishing is basically getting the metal flat so it reflects light, thats why it shines so if you use alot of chrome or aluminum powder, make sure you have a really smooth surface.
3.Black Magnum: Provides an etch which acts as an achor for the powder to adhere to. Great stuff and its cheap get it in either meduim of fine grade and it is recommended that when using this stuff you sand down the piece with 220 grit sand paper, it knocks down the profile a bit and gives you a better inspection of what you will be coating
Thats really it, I am sure people use others but these are the medias that come up more often.
What do I use? I mix a 50lb bag of fine black magnum with a 60/120 bag of glass beads and a 15lb bar of walnut.
Why do I do this? Because I still get the achor effect, and the smoothing effect of the glass beads, it also keeps down the dust and if you have parts like aluminum this mix will not eat the metal and create pits.
I would recommend using a pressure blaster at 80 with the mix if you try it and dont blast close, give a good distance like your painting the part your stripping, slowly fading the surface and blending the profile evenly.
