Soda Blasting Updates?

[Chief Engineer]

I looked at some of the old posts about soda blasting.

Is there anything more up to date development/experience wise that anyone has had heard of.

The old posts were 50/50 good and horror stories

::actively lurks:: I need to strip the bottom of my boat too, sometime after this coming summer, so I'm looking at this information as well.

Low preassure warm water lava blast is the latest and greatest that I'm aware of for pleasure boats. Easy on the boat and does not impinge material into the hull like high pressure does. Prices are pretty reasonable we were told about $2k for our boat, 61 foot.

Do you have a link?

From Wikipedia:

"ʻAʻā

"ʻAʻā (also spelled aa, aʻa, ʻaʻa and a-aa, pronounced [ˈʔɑʔɑː] in Hawaiian English, from Hawaiian meaning "stony with rough lava", but also to "burn" or "blaze") is one of three basic types of flow lava. ʻAʻā is basaltic lava characterized by a rough or rubbly surface composed of broken lava blocks called clinker.

"Pāhoehoe

"Pāhoehoe (also spelled pahoehoe, pronounced /pəˌhoʊeˈhoʊe/, Hawaiian English, from Hawaiian, meaning "smooth, unbroken lava") is basaltic lava that has a smooth, billowy, undulating, or ropy surface. These surface features are due to the movement of very fluid lava under a congealing surface crust."

The third type of lava is:

"Pillow lava

"Pillow lava is the rock type typically formed when lava emerges from an underwater volcanic vent or a lava flow enters the ocean. However, pillow lava can also form when lava is erupted beneath thick glacial ice. The viscous lava gains a solid crust on contact with the water, and this crust cracks and oozes additional large blobs or "pillows" as more lava emerges from the advancing flow. Since the majority of Earth's surface is covered by water, also most volcanoes are situated near or under it, pillow lava is very common."

For a more detailed explanation of the three types of lava, go to:

I now have this image of sailing my boat out and anchoring over an underwater vent...

I had our boat done last year. Excellent outcome. Took the old paint layers off down to gelcoat without any sign of damage to the gelcoat. I still had to sand the whole hull to take of the last remnants of the first coat of paint to completely clean the hull, but that was far, far easier than stripping. Ensure the operator has boat experience.
