SPI Epoxy over PPG Epoxy?

The shop that is going to media blast my project for me uses ppg epoxy. I asked them if they would use SPI epoxy they said there never heard of it and will only use ppg. Is ppg epoxy a good enough foundation then move on to spi?
 
Which ppg epoxy are they using? I use ppg at work because I am forced too, I like the new dplv epoxy. U can actually sand it. Dplf sucks imo.

But if I had a preference Spi all the way.

He said ppg Dp epoxy. I'm not familiar enough with ppg to know if there were different types of dp. There's a few other shops i might try calling but there quite a bit further away
 
Why not take it home raw and do it yourself?
I would bet they will not be as anal as you will on cleaning it before priming.

The DPxxLV is a newer product and reportedly sands far better than the DPxxLF, BUT the DPLV is getting a reputation of not sticking to bare metal very well. But that again is internet hearsay as I have not used it.

I would suggest either taking them the SPI Epoxy or taking the car home raw and do it yourself.

That is how I recently did my 65 Mustang , had it blasted, loaded back on my trailer. wrapped in 2 bags, then duct taped and tarped. Came home nice and dry on the winter roads.
 
Primer it yourself, you'll also do a better job of cleaning/prep work I bet. What kind of media are they using?
 
Glass bead is what they were going to use. I'm in new england and worried about flash rust taking it home raw. Maybe I can try to sell them on spi and use my truck as a "demo" at their place. So I'd still be doing it myself in a booth and it won't
Insult that I'm doubting there work either.

I've been in the same situation.

I've tried having the blaster use PPG epoxy on a set of tractor rims. They aren't holding up to the calcium chloride and normal abrasions nearly as well as another set of tractor rims that I did with SPI epoxy.

I tried having the blaster use SPI. They charged me a lot of money to spray a light coat and left bare metal in a number of places. It isn't a big deal to spray more epoxy when you get it home, but as was mentioned already, you are trusting the most important cleaning step to someone else.

The best way is to work the weather. I'm assuming they can store your car inside for a day or so. Pick up the car when weather conditions are best and spray it yourself.
