Stripping a frame back to Alu' - what's involved?

Great advice guys appreciate it a lot. Just another Q though, is it worth clear coating it once I've stripped it back or not really?

I've heard of people doing this without issue, but, I've also seen people use the wrong clear coat. If it's too inflexible, the clear coat will crack and oxidation will occur underneath. Shows up like spidery white marks under the clear and then you have to strip, Polish, and seal again. Go for the car Polish and a little bit more maintenance every couple of months.

not necessary and can give more issues down the line.
