Bright, Shiny, and Polished Objects

I would say that any blasting process requires you to take apart whatever you're blasting. Wire brushing, and other scrubbing also requires good masking but they are not nearly as problematic.

  I agree BDA,  blasting an item is contaminating every orfice, bolt hole , vent passage. Disassemble, flush and clean afterward.
  Tom or Andy, these are the pics I think you might have seen.

That would have been Tom.
To give a idea of my type of polishing, a friend asked how i kept the paint on my Toyota truck from fading, since it has some years on it. "I never wash it", my reply.

[dakazman]

   That looks great.

   I have a tip from another venue to paint with,”aluminum last blast’” paint . I have not researched it or tested, but it was highly recommended.  I still haven’t searched for where to purchase it.

Hey D, the LS rebuild in my wife's Cadi I posted in the off topic section is sprayed with Goodson Aluminum Last Blast.  It looks fantastic, I was going to use it on my Europa transaxle.  I hate the aluminum oxidation on the raw blocks and casings.

Thanks Eastwood doesn’t Carry  it but a place called Goodson’s does according to google.
I was going to polish it but I just can’t afford the time. Lol and I’m retired. The nickel plating all the bolts and other brackets is a much better investment of time.

Sounds like there are plenty of reasons to be cautious about blasting, although, do these concerns also extend to soda (baking soda)

  I had good results soda blasting a mahogany dining room table with intricate carvings . It was a mess outside, and visibility was difficult.  The cleanup was next to nothing as It washed away, so Yes for me to use.
As I was nickel plating all the gearbox bolts and brackets I found the aft section bolts that were installed, torqued, sealed with blue silicone gasket material, the bolts when extracted had sand blasting residue in the threads and tip. So someone previously blasted the gearbox and assembled it without cleaning the bolt holes.  Just don’t be that guy!

   Back to shiny, I picked up some wiper arm assemblies from eBay . I’m glad the owner didn’t polish up the stainless before selling them.
  Put my stainless buffing pad on the buffer and with green rouge had it back to showroom condition.
Some before and after pics.

D'man, your car is going to be one "shiny object!" 

[surfguitar58]

Nice look D’man! Are you doing any kind of passivation on your stainless? I hear citric acid is pretty effective and not too dangerous for the home brewer.

[dakazman]

   No I haven’t.  Thanks for the term. I have been reading the meaning and procedures of passivation.
I have not done it in the past and still not sure if it’s needed. I will continue to educate myself and read.

   Finished the wipers and most of the hard side of the engine. All The nooks and crannies took Ali of time to sand down. I should finish tomorrow.😀👍👍
