I don't know how well the tissue and dope will take details (rivets, etc ).

When glassing, typically 1/2 oz (.5 oz) or 3/4 oz (.75 oz) fiberglass cloth is used.

There are 2 basic ways to apply the cloth. The 1st way (traditional way) is using resin. The 2nd way is using a water base polyurethane.

The polyurethane method has about 60% of the strength and rigidity of resin, HOWEVER, it only has about 50% of the weight and is A LOT easier to sand. The polyurethane method is (IMHO) a lot less of a mess, and has almost no odor and no fumes. I admit that I am a big fan of the polyurethane method.

Here are instructions for the polyurethane method. The basics would also be the same for using resin.

Sorry I read this thread late,
Question, what brand of polyurethane are you using? I use resin now but always willing to try other methods.
