Clair,

The catalyst you are mentioning would replace the part B Hobby Poxy Correct?

The part B is the next thing I will run out of.

I had heard that lacquor thinner / reducer would work as thinner, but I haven't tried it yet. I'm still a couple of weeks away from using the paint. I have some Dupont on the shelf, but I also contacted Pettit Paint company to ask them if they had a recommended substitute for the Hobby Poxy thinner. It turns out they still make two part Epoxy paints for boats and they tell me to use Pettit 97 thinner available at most marine supply stores. I checked the West Marine web site and they carry it for about $8 per quart; so my current plan for thinner is to get the pettit stuff.

It would likely turn out that many solvents would work OK as thinner, but may effect how well the mixed paint brushes out or sprays on. In reading the Hobby Poxy "paint tips" brochure I have had around for years, they talk about solvent trapping - probably if the solvent is too slow to evaporate. We know that wouldn't be the case with lacquor thinner, but might be with say alcohol or a slower evaporating solvent.

The use of the catalyst from Norm Duhit Aero is great information to have as I'll bet there are thousands of cans of part A Hobby Poxy sitting around on modelers shelves.

Thanks !

Sincerely,
Ned
