Greetings

I recently bought one of the Israeli trade-in CZ's. It's an aluminium frame P01-predecessor. The finish is terrible, lots of holster wear and plenty of chipping in the poly-coat. The frame will need sanding in some places before repainting too.

The question is, what is the best way to strip the frame of the old CZ poly-coat remnants? The slide is steel and I'd just sandblast it but would that risk eating into the aluminium of the frame? Or is there some wonderfully horrible solvent that will eat through the armor CZ calls paint? And after its stripped, after I've undercut the trigger guard and cut another notch or two in the rail on the dust cover, will this need priming before paint, being aluminium? I had the idea of getting a can of Brownells ALumahyde to paint the frame and slide after stripping.

[This gun is nowhere near nice enough to keep as a collector. It's a shooter and will be my EDC]
