TRUEGARD Mineral Spirits Petroleum Solvents- 105 Flash Point - 55 Gallon Drum
The BEST !! Better than the rest !

My usual supplier of odorless mineral spirits had heart stopping price increases and then their product took a nosedive. I confronted them about it and they had nothing for me, so now I'm on the hunt. Google brought me to Keller-Heartt Oil when I searched for low flash odorless mineral spirits and the price was so reasonable I was sceptical, so I payed with PayPal and let er rip. Boy ! Am I happy ! This is without exception the best solvent I have ever used in my 30 years of auto machine experience, it dries quick and the parts are soooo clean, I bought two more drums. If I could I would fill a small warehouse before the prices go up. It's that good, you won't be disappointed. Go Keller-Heartt !
