We washed a White vinyl sided house with rust on the front. The lady said the last two power washer's couldn't get the rust off. Well we showed her how it done. Three coats of Craigs F9 and it was gone. This is realy good stuff guys if you havn't tried it yet.
Art. Just FYI we do have a new msds out as well. It was important to disclose that it has a small amount of Ammonium Bifluoride Salt which produces about 0.3 to just under 1% of HF in solution. It's not enough to burn bad but still be careful with it. Just want to make sure you wear gloves and PPE.
Here is the MSDS for F9 BARC for those who'd like to keep it in their truck.
They are changing quite a few things lately. I'll be taking some classes and getting DOT Certified next month. The classes I'm taking is a "train the trainer" courses so I'll be able to teach and certify people in our industry as well.
Guy, Craigs product is the ultimate in rust removal. It works great on roofs. DONT LET IT DRY. I sent my guy Anthony to touch up rust around a chimney . He's an island boy with a thick Rastefaren accent. He'll do whatever you tell him. But I didn't tell him to rinse after spraying F9. Long story short it cost me $3000 to replace the shingles on the back of the roof. The F9 release the patina from the copper chimney flashing and it funked everything up. Still love F9, just be careful.
Ed, I just checked my house phone messages and heard one from you. Please keep my cell phone on hand and text me to get ahold of me anytime.. I can normally get back to you in 5-10 minutes if you text me (just please remember I'm on the West Coast! lol).
I'm so sorry to hear about the roof. I still want to talk to you about it and see some pictures if you have them.
F9 some good stuff for rust on siding!
F9 is some powerful stuff! Great before/afters!
F9 is great. My 1st time using it last year on an asphalt roof. 1/2 hour in and out. Thanks Craig.
