Here are the tips I'm planning to install soon. I originally purchased DiMisa tips in black powdercoat. The powdercoat turned out to be polyester based, which is what I think they use on outdoor furniture. Tips appear to be great quality. I decided to coat them in a thermal ceramic coating for longevity. At this point I had already spent more than one should on tips, but made it worse to get them coated. Took them to Houston Cerakoters and they were extremely helpful and fair. Tips looked amazing. They want to get into more auto part coating and asked to photoshoot the //M after install...I left that place and 3 minutes later had the accident :-|
A little about cerakote: 9H pencil hardness; low coef friction results in 5000 wear cycles for each thousandth of thickness; tested in salt solution for rust resistance; 160 in-lb of impact force with no cracking/flaking.
