If you find another product that you like better then of course use it. I would.
I just ordered and used my first SPI epoxy and am a new convert. it sprayed perfectly with a 1.4 tip. It actually had enough build properties that I was able to block it out for a small repair. It sanded well and did not clog the paper as most Epoxies will do. I personally believe it is the best I have ever used and am anxious to try their other products. While Epoxy is not billed as a high build primer to be able to do some moderate building with it is a real plus. Instead of using an Epoxy primer, 2k high build primer, and sealer it allowed everything to be done in one step...... Prime with epoxy, block and paint. Ain't life grand?
Just as a matter of record, I have been using PPG DP40LF up to this point.
