I just used some Hi Temp Silver last night on some headers and when cured it kind of had a texture to it like blasted aluminum. Has anyone used this, and is this typical? Bottle says it is only 15% gloss. I have only shot gloss before this. Do the Satin or Flat powders usually have a texture to them? I let cure at 425 for about 35 min. I also put these in cold and the oven took about 25 min. to come up to 425. Other than that it seems to have covered really well.
