Alittle off topic but maybe someone can help.
I build RC boats from balsa.
Boat #1
Built the boat.
Used Krylon primer till the grain was filled.
Painted with Krylon paint.
Then krylon clear.
1500 grit and polished till light glass.
6 months later the paint was Crazed everywhere.
I thought that maybe I didn't let the layered set long enough.
SO......
At this point the boat cured almost a year.
I 600 sanded, krylon clear again, worked it till like glass, 6 months later, Crazing everywhere.
Boat #2
Same process only I let the color set for 3 months before clearing, worked it to a glass finish and 6 months later, Crazing everywhere.
What gives?
How do I fix it and prevent it next time?
