What I do is just expose the dirty isopropanol to sun or UV in general - the resin will precipitate. Then just filter it out and you have clean isopropanol.
That shouldn’t produce clean isopropyl, but rather, isopropyl with fewer polymers and the only resin you are curing with the sun is what is settling to the bottom, TBH. However, your process is good if you only use a batch of IPA for resin washing and eventually dispose of it.
If you were to spray that isopropyl on some glass, it will leave residue of some kind. The more you use the isopropyl without distillation, the more contaminated it will get with other solvents and photoreactors.
My goal is to produce pure IPA that I can use across my hobbies.

I see, to be honest I have not checked how clean it actually is. It is visually transparent, as opposed to the used one, but you are probably correct.
