I recently started painting a guitar i am building. I sealed the woodgrain pretty well, or I thought I did, After putting on the first 2 layers of primer I noticed several flaws I hadn't seen before, and several spots where the grain was hardly sealed. In the pdf file from howtopaintyourownguitar.com suggested bondoing over the primer to fix any problems you see later. I bought some bondo, and started trying to cover some of the flaws. The primer melted everywhere I put bondo, I decided to just let it dry and see what happens. It dried and it apeared to have set up just fine and it is bonded to the primer/wood just fine but there are cracks everywhere in the bondo.....
If anyone has any ideas about what happened or how I can fix it, please help.
Thanks!
