I have been noticing paint crazing on some of my recent models that appears around 6 months to a year. Consequently I on my latest model a Trumpeter Attacker I tried a slightly different paint build up. Normally I use Tamiya primer followed by Mr Color acrylic and then sealed with Klear ready for deals with finally a coat of Mr Color Matt Varnish all applied via airbrush.
This time I thought I would give Humbrol's new Gloss acrylic a go, replacing the Klear.
This is the model before application of the Humbrol which I applied yesterday evening
All looked fine but when I woke up this morning I was greeted with this!
Grrrrr.
Any ideas what is caused this? My suspicions are pointing to the Mr Color or to the warm temperatures we had while the varnish was drying.
