Paint Stripper vs. Sandblasting

On the couple of tractors I've done, I've taken everything off from the main body (engine trans, rear end) that will come off and sandblasted. The body I used stripper on and then wire brushes using air tools and small 4.5" angle head grinder with wire wheels.
Sand ends up everywhere and I'm not brave enough to sandblast the engine/transmission although I know people who do. I think what paint remains if it survived paint stripper and wire wheels its not coming loose.

I use stripper on everything now as it cuts down on the amount of sand to buy and wear and tear on the compressor. The last 8n I did I used 5 quarts of stripper and did the whole tractor. Sand blasting is a snap if its stripped first.

Watching this thread with particular interest. I am at that point in Fergy restoration where rust removal and re-paint is the next step.

Bruc. No reaction between the Sodium Hydroxide and the aluminum in the transmission casing and other areas?

I was considering sand blasting but have serious concerns where the grit may end up! I'm now trialing a local product "One Step Rust Converter & Primer/Sealer" by Motorspray. The container says:

"In one step it chemically reacts with rust and converts it to a hard inert organic compound and then seals the surface with a tough impervious coating that is a suitable base for subsequent coats of paint. Recommended for the treatment of rusted steel and galvanised surfaces whenever it is not practical to remove the rust completely.

Suitable for use under most paint systems. May be left up to 3 months before priming and top coating. For 2 Pack paints allow 24 hours drying at 20 deg C."

Interestingly, the product appears to convert the rust and form a very hard enamel like coating over the metal.

Only trialing. Not recommending!!
