I'm running into a really weird issue and wanted to see if anyone had any experience / advice.
I'm spraying Target EM7000 waterbased "laquer". I spray around 15 coats, then let it cure for a couple weeks (although below phenomenon also experience with a body that I'd let cure for 4+ weeks, just due to not having time to get to ir). Then level sand with 1000 grit and move up to 7000 before taking it to the buffing wheel. Using the Stewmac buffing wheel with Menzerna GW16.
The issue is this: using just this one compound I can get the finish to a really good shine, with sharp specular reflections. Buuuuut.... wait a few minutes (presumably enough time for the surface to cool down again after buffing) and a certain amount of the sharpness disappears. It's like the heat causes the finish to expand slightly and it's super glossy, but then it cools and contracts slightly and small surface variations come back in and the glossiness is slightly less sharp.
Anyone come across this and have any advice? Is it just that I also need to do a pass with a finer compound afterwards? Is this just a drawback of using waterbased fiinish? Any advice?
