I’m new to modelling, took it up as something that I could do while my surgery healed over so I basicly know nothing

I used a Humbrol matt white enamel spray as an undercoat recently on a republic star destroyer kit, it went on fine and I proceeded to panel the whole thing using thinned black paint. Again everything went to plan.

Then I went to add thinned light grey enamel (Revell with Revell thinner) to the base coat and disaster, the basecoat started blistering/lifting must like the lifting section of this page http://modeltech.tripod.com/paintprobs.htm though much less severe (still enough to completely ruin the paintjob)

Two questions:

How do you check whither your paints are compatible and won’t cause this effect?

And

Is there any way to add some sort of coat to an undercoat that’ll stop this from happening?

I have a million other questions chasing each other though my head but right now they are the main ones

Thanks in advance

Thanks, I’ll buy some clear matt vanishes and pray nothing else goes wrong.

As for buying an airbrush atm it’s not going to happen for several reasons.

1) Way to expensive for something that I may or may not continue once I’m fit and healthy again.

2) I’m barely competent with brushes, twenty or thirty more kits and if I’m still building models I’ll splash out and buy a good airbrush kit.

3) I’d prefer to learn the basics before doing something more advanced; every weathering technique I’ve tried has ended in disaster. I have a binned Jedi Fighter, a bronze X-wing (I blame the painkillers) and a barely passable Tie fighter that’s more white and black that light gray and black.
