Just joined, Rick @fuzzmann!
Good luck with your attempt!

Hi Aleks,
Yes, the first two tries were applied over Tamiya Fine Grey Spray Primer which I had used with success with Mission Models Paint before. I was quite surprised that the Gloss Blue Sea Blue wouldn’t adhere, as I had had no problems using MMP’s Flat Colors.
My first try with MRP GSB (#3) was also my first time using that brand of paint and I discovered that using it was similar to using a metalizer in that it showed every flaw, and that a consistent undercoat gave the best result.

Hey Rick, @fuzzmann
My 1/48 Monogram "Bridges of Toko Ri" F9F Panther jet has fought me every step of the way too. I had to strip mine down too, removing the paint AND the filler work accidentally, when my paint job was an epic failure. It's almost done now, I'm just hesitant to get bitten again... Hang in there buddy, don't give up.

I'll finish mine if you finish yours... Deal ? Don't toss it buddy...

Hey Louis @lgardner
I knew you’d had to do a couple of repaints but I figured you had finished yours by now.
I’ll keep flogging this dead horse and see if I can drag it across the finish line.
I’m going to unmask it tomorrow, and if that goes ok then it’s on to the decals which has its own perils.

Happy to see the flogging gave good results -yiihah. . . .
