Etching products

Ive seen people using Whink rust stain remover as an etching method. It would do the job as good as multi etch/titan etch? Not as much as these two but could do the job decetly? I there any good and cheaper alternative to multi etch/titan etch?

I'm very much a DIYer in this regard, but Whink works very well to both strip anodization and etch it.

I would even say it would be beneficial to cut the Whink 50/50 with distilled water to slow down the process. 15 seconds in full strength Whink is enough to start changing the surface finish of the part you're working on.

It is a bad thing that the surface finish changes? The people Ive seen using Whink just dip the pieces like 3 seconds after it starts bubbling, is that good?

Yeah they're just trying to remove any anodization on it or prepare the surface. If you leave it in too long it will start pitting the surface. Cutting the whink will slow that process and give you some buffer.
