So I did it. I managed to get a a sample of the Pink Soap, and liked it. A week later, I bought the 5 gallon bucket!
I used it over the weekend on a "client" car that had some bug splatter on his hood. I presoaked it, sprayed some Bug Remover across the hood, and followed up with a 2 Bucket Wash. I was pleasantly surprised that it got rid off all but one! No high pressure system either, just standard hose. Cool deal.
And with 5 gallons of this stuff, I'll be handing out samples to friends and co-workers.
