A few things you might need to understand about Wet Blasting / Vapour Blasting ?? You need to be a Patient person. They are not like a Sand / Garnet Blaster. They're more suited to Fine Finishing work. IF you want to remove, Paint or similar coatings this might not be the best choice ??? But, IF you want a nice clean finish on most metals this might be way to go. Also be aware that Ferrous Metals will almost instantly start to air rust after you finish Blasting ??
