stopper / filler or primer shows up in basecoat

[carl0s]

Hi.

Unless I apply lots of coats, it seems like my repair areas (e.g. dolphin glaze) show up in the basecoat a lot, even if there's primer over it. Usually don't see it until I hit it with the base coat. enough applications of base coat seem to hide it though.

For example, I have used a little body filler, and then glaze, and applied 2k primer over the whole panel, and sanded to 800 grit, and it all looks like a nice primed panel. I apply the basecoat, and then the repaired area shows up like a sore thumb and I have to cover with a lot of base coat to hide it.

Is this normal? is it just that I haven't sanded properly and so some coarse lines are showing through ?

are you filling on top of paint ?

Yeah. I'm mostly talking about dolphin glaze though, on plastic parts. It says you can use it over anything, can't ya?

its usually repair edges that show through, ie the edges of the paint you have sanded id sand a little further, repair prime flat it and a further coat of primer and carry on

OK thanks I'll try that.

You always have to prime a whole panel? All the 2k primers I have looked at said "entire panel only". Is that how it has to be?

ive spot primed loads of times I never do a full panel if I dont have to it depends how much of the panel needs it I suppose if its quite a big area then may aswell do the full panel, less edges to feather out
