I have slowly made my way over to the right side of the skin. Every day I would put some Testor's Model Cement in a small area and clamp it, then repeat the next day.
However I am also noticing a few problem spots I need to fix.
For example, the horizontal panel has some seepage from using contact cement that needs to be cleaned up.
And, every R2 Builder goes thru this...discovering the skins, despite your best efforts, are crooked or off a bit. I'll just wind up using an razor to fix the octogan port.
