<div>Hi Guys, I have a question on sandblasting my hull parts. The
initial fabrication is almost complete and I was thinking that I might
want to have the parts sand blasted prior to welding them all together.
Maybe even a light primer seal coat to slow flash rust as it may be at
the welders for a couple of weeks. Any thoughts or advice would be
appreciated. I know right now every time I get near the parts I'm
covered in black smudges.</div><div><br></div>
