Paint hazy after coolant spill
Here is a safer alternative....
Get a bottle of Meguirs #7 Show Car glaze. Only #7, nothing else. Do not apply according to the directions. (Like any of us read directions.)
Lay it on heavy and leave it on thick and gooey inside a garage overnight. The next day, put more on and wipe away what you have. Then buff it out.
Meguiars #7 is a very old-school polish. It actually leaves behind an oily residue designed for Laquer paints. Since your paint ahs been "de-oiled" this process will attempt to put the oil back into the paint. This process only works on old paint and does not work on BC/CC or 1-stage. Only old paints.
Its worth trying if you have "dried" your laquer.
Good luck,
