I assume your referring to me?

Yes it did, left the gelcoat feeling like 100 grit sandpaper but was able to sand/polish it back to a nice shine!

I'm all for the DIYer, more power to ya. That compressor should work alright with a smaller pot setup, youre just gonna have to play with the air/soda flow. I assume its white paint, so tread lightly as its difficult to see how much youre taking off at times.

Theres a lot of different variables that go into how the subsurface comes out after being blasted. Prep, what it was painted with, air pressure, adhesion, etc. Generally we're blasting paint off boat bottoms and how it was prepped prior has the biggest impact on the surface.

Its grey paint so its pretty easy to see actually, im picking up my compressor tomorrow so i will see how it works this weekend with the blast cabinet gun i have, if it doesnt work i might try a harborfreight soda pot, if it doesnt work i can always return it and get a better one

The gun im using is like the one in this video http://www.youtube.com/watch?v=scBYl...feature=relmfu

The Harbor Freight one is just a regular media pot with a small fitting on the bottom to shoot soda. I have one we used for small stuff, it doesnt work bad as long as you have dry air. I'm on the road doing the bottom of a boat until tomorrow, if I can find it I'll take a pic for you so you can save some cash.

If you are looking to get rid of that Harbor freight one let me know. I was thinking about picking one up just to mess around with.

I think they have a dedicated one now, the media seems to come from a pickup and out the top

I went through this a while back, I ended up buying an Ace pot. I wanted something for occasional use and it was a deccent compromise between a cheap HF unit and spending 9k on a Soda Blast Systems unit. I've ran some fairly wet air through it on humid days and yet to have a clogging issue. I've used it mainly bottom paint and started experimenting with other finishes. I started running it on my shop compressor (80gal. 325 Quincy 7.5hp). I can open my main regulator up to 175 psi. and set my reg on the pot at 100 psi. and the compressor will run non stop with 80psi. on the pot. Aside from being a little slow it works OK on bottom paint and burns through the thin spots of epoxy, it barely scratches where the epoxy was done right. If I hook it up to my 185 Ingersoll and run 100psi. on the pot with the fan nozzle on the hose it covers a lot of ground in a short amount of time. Harder finishes need more pressure than what your normal shop compressor is going to put out if its free flowing. You might want to look into a more agressive media, it would help a lot if you could find out exactly what kind of paint that your up against first.

One other thing that you need to know about soda blasting. You have to "neutralize" anything you blast with soda before painting. Some say warm soapy water works, but I've had the best luck with vinegar.

Do i have to neutralize before laying glass.. i was just going to clean with acetone then isopropyl alcohol

I really don't have an answer for that. VC Mike or Glassdave might. I left the boat (project) totally uncovered when I blasted it and half of the boat ended up with piss yellow stains in the gelcoat. I test cleaned a spot and it took some fairly serious buffing to get through the stain. I dumped vinegar on it and within a few minutes I had shiny white gelcoat again.
