i found that has home depot has and pulverized limestone - $4.60 a bag for 40 lbs.

can i use it? i have to find a fine sand for cheap. any advise will be great.

 

well... my suggestion would be to not use sand, especially on the panels. There's a reason high end companies no longer use sand blasting as it heats up the metal quickly and can cause them to warp. I would suggest soda blasting which is a fine baking soda, basically. It does not heat up as badly as sand, and keeps your parts from losing their shape.

If you must use sand, Then give it a try. I would like to know if it works, and if not it's 5 bucks!

and some other advice, check your spelling and sentence structure. Your post was kind of hard to follow...

 

i'm sorry:

first you need to know what Limestone is...
Limestone is a sedimentary rock composed of Calcite.

Calcite is Calcium Carbonate (CaC03).... dead shellfish mostly mixed in with large amounts of sand, Now i will never use sand again because it can cause Silicosis.

Silicosis is a pneumoconiosis, or lung disease, that is caused by the inhalation of toxic, carcinogenic crystalline silica dust particles. Silicosis is incurable and irreversible. Silica is a naturally occurring mineral that is found in quartz, granite, and other rocks. It is one of the most common minerals in the earth's crust, but it is only harmful when small particles of it are released into the air and inhaled. Unfortunately, many jobs require workers to use tools and equipment that introduce dangerous levels of crystalline silica dust into the air. Once silica dust is airborne, silica exposure is difficult to avoid, especially when working in tight areas with high levels of silica dust for prolonged periods

In other words not a good choice.

I would call around and see if there is a company in your area that can blast the stuff for you.... you might be suprised at just how cheap it is. (i had my frame and 10 other parts done for 200 bucks)
stop by the local harbor freight store and look into the soda blasters they have. baking soda is bio-degradable and not harmful

one last thing.... ask yourself, do i have a compressor big enough to sandblast in the first place. it takes large amounts of air.

 

Or use your 3500 PSI pressure washer and a pressure blaster kit from Northern Tool. No dust is created when using plain clean sand. It also mitigates heat warping as the medium of water carries away heat along with the old paint and rust.

I am going to try this on my crew cab frame and parts.

hey that just might work

 

Limestone will cause rust very quickly as it is a base. You will need to rinse it with tons of clean water asap!
