Cave I would use a 3.0 tip gell is thick I use a SATA LM 2000 with a alum cup.
Quart of mixed gell consist of
80 percent Gel
20 Styrine
20 cc hardner
2 cap full of wax sol from the wax can (this is how I was tought I never measured it)(leave in the sun to heat up)
Like I said some guys use diffrent stuff like some use PVA I think it is some reduce it with Asatone(my gel suplier said this is a no no because it breaks down the gel.
