I promote brands that I like like Ospho RustMort and others even though we have a great rust remover and prep, As far as the test goes I bought the qt from SBI followed their directions . 15 days later I wiped it off with lacquer thinner.There are thousands of cars out there with our products on it. And with over 20 years doing shows never any problems to speak of.

Who is SBI? I know my SPI has worked great and is the only primers I use. Never had an issue with them. Maybe you bought the wrong brand and don't know any better.If SPI didn't work as advertised I would be the first to say something, but the fact is it's a great product. I have used it on several of my own projects (including SPI clear). Nothing, but good things to say about it and I tell everyone that will listen to give it a shot. I have never heard anyone that tried it have a complaint.

Your laquer thinner test is BS, I have wiped SPI Epoxy with laquer thinner and it never harmed it. You did mix part A and B before spraying, right?

What point are you trying to prove anyway? I'm a little confused why you would come on a forum and bash a product. Let's assume you actually had an issue with it, why wouldn't you go to SPI (Barry) with the issue? Anyone that has used SPI knows that Barry is only a phone call away.

If others say it is insoluble, then maybe you should look at your test? The old scientists motto "When an experiment yields unexpected results, challenge the experiment".

I know I thought the an experiment I had done on weld thru primer showed how poor it adhered and then Barry told me to re-test it after a week or so, sure enough it was TOTALLY different after that week.

If others are saying it is insoluble, then I would look at the conditions of the test somehow, temp, was it fully cured? I don't know but this is odd.

I can understand being upset about a products results and screaming it from the roof tops. But this whole thing just sounds odd.

Go do a test if you have the SPI epoxy primer in your shop and report the results, that should solve this.

The point is, why paint stuck better to the epoxy and I showed you, and yes I mixed the a part thoroughly and thoroughly mixed again with the hardener Do your own tests, I did not bash sbi although Barry loves to bash everybody else's brands as in his latest rant

By all means do your own tests. I'm just saying what I found .Epoxy with high fill have less solvent resistance than some others. Maybe I'll do it again, Good Luck

it was done in my shop was about 70 the panels are about room temperature. I brushed to coats two hours apart. my point again was sometimes you can wipe hard primer that cant be sanded to soften its so another paint would stick better. I wasn't planning on an a FBI investigation

You let it cure for how long? If you just did this test today, there is no way the epoxy was fully cured and locked down.
