I don't have hardly any experience with spotting glaze but heck if I have to much more troubles I will look into it 007, thanks !
I did another over pour and promptly sanded way to much so #4 touch up yet tonight.
But I did make a accidental discovery that has some implications to which I do not know the full extent but for me in my project I took the canister to 1000 grit all over and when I decided to take the hobby knife and "v grove cut" the area I am working on instead of using rubbing alcohol + Q-tip to clean area I used carb cleaner.
I done the same a few minutes ago prepping for the 4th. touch up attempt at witness Mars.
Gum out carb cleaner put one heck of a nice satin sheen on the plastic with no sticky mess,,, just a very nice finish.
That was with Q tip, going to have a go at spraying direct from can layer on.
Perhaps this discovery may be of help to folks sanding fenders. Heck, may be already known trick already ???
