These are all great points.
I will not buy from chemical suppliers unless I test something first, I would buy all kinds of things in the past only to find out that I wasted not only time and money but then I had to get rid of the worthless chemicals at my own expense and time.
Unless there are guys on the forums that have tried the products, I might buy a sample and pay for shipping but long gone are the days of buying drums or drum kits of something that I have not tried out first to make sure it works in the real world and at real world ratios.
I don't hate chemical vendors, just the ones that lie about the ratios, lie about what it will wash and lie about how good it is, especially if they have never washed out in the real world in the past or recently to know what it takes to make a good product that actually works out in the field.
I have bought Steve's products in the past when he had his website and forum and they were good products so I am sure he has something good or he would not be promoting it.
Since this product is non-hazmat, I would think that it could be measured out to make a 5 gallon bucket and the shipping does not even have to be ups or fedex, it could be thee usps priority mail for about $8.00 or less for up to 4 or 5 pounds or what you can fit into those free boxes they give out to promote the priority mail. This would help keep the shipping part down.
I would even be interested in this if I could test at least a 5 gallon bucket or two to see how it does compared to what I normally use.
