As for the chemicals, the anodise and chrome stripper is Potassium Fluoride, the DeOx/DeSmut is a mix of sulfuric and phosphoric acid, the Sealant LT I am not familiar with because I use the regular sealer which is nickel acetate.
At this time I do not use the stripper because I physically strip the parts by blasting, sanding and polishing or a combination depending on the look I want for the part.
The DeOx/DeSmut can be substituted with common lye (sodium hydroxide). It can be usually found in most drain cleaners here. Start at about a 10% solution. The problem with this solution is it is not as predictable on the results as the Caswell product. You need to test times and concentrations for best results. It will also take the shine out of a polished part if left in too long.
I am not familiar with Metalbrite. Do you know the ingredients?
As for sealing, I have had good luck with boiling to seal. I haven't been able to see a visual difference between the parts that were boiled to seal and the ones that I used sealer on.
One thing you haven't said anything about that is important. The water to mix any of your tanks and for rinsing between tanks needs to be RO or distilled. Rain water can be used.
If you can swing it, the Caswell plating manual has a load of information in it. You can get a hardcopy or online version. Between it and the guys on the forum, it didn't take long for me to get good results.
If I missed anything or wasn't clear, just let me know. Best of luck. SS
