You are kind of new to the forum and I hate to be that guy, buttttt.....
You are supposed to contact the shop/seller/manufacturer before venting about poor quality, functional issues, etc.
Screwball says they are good to work with, and if they address the problem - or if the problem turns out to be the first person who worked on your pistol - it kind of paints an unfair picture.
Reference reapplication, the problem is the penetration into the surface of the aluminum: https://www.anoplate.com/finishes/hardcoat-anodize/
All anodizing is a conversion coating in that a portion of the base materials surface is converted from raw aluminum into aluminum oxide. In general terms, for Type III anodize ½ of the coating thickness penetrates into the surface of the parts while the other 1/2 builds up on the surface. Thus for a typical 0.002” thickness requirement, there is 0.001” dimensional change per surface.
These guys, however say it can be done: https://www.pfonline.com/articles/an...nodic-coatings
Sometimes, when stripping the Type III coating, the coating does not strip evenly, especially if it has been sealed. This results in blotchy areas on the part where some of the coating remains after other areas are completely stripped. As a result, you could end up with an uneven surface on any of the surfaces, masked or not masked. Nothing short of resurfacing with a cutting or grinding tool will make the surface even and smooth if this happens. If grinding or cutting that surface will put it out of dimensional tolerance, then you have a problem.
A good practice to follow when stripping all heavy anodic coatings is to soak the parts, or the loads that are to be stripped, in a strong acid bath such as the deoxidizer, or even the anodize bath, for up to 45 minutes, rinse and then strip the coating off. This method breaks the seal, if the parts have been sealed, and softens the coating, making it much easier to remove completely and evenly.
Using a “non-etch” stripper is also an excellent way to strip the anodic coating off of the parts without removing any of the substrate metal. However, if some anodic coating has leaked under the masking, it could result in an uneven surface anyway. This is because of the penetration of the coating in that area.
Zincate-based products are commonly used in non-etch strippers. A non-etch stripper is a chemical solution that will remove the anodic coating (aluminum oxide), but will not remove any aluminum metal.
FWIW
