I'm a new guy to the forum. Getting started on a 10. Is anybody using the Sanchem 6100AB and Cleaner with the 3400 sealer #2. I'm thinking this is a safer product, but curious if you think it will work OK.Thanks T.O. Craig

No experience with the Sanchem stuff, but if you are interested in something that is safer, then checkout AFS. I'm pretty happy with their stuff.

I'm using the Sanchem w/ Sealer for the interior of my empennage. It's safe and so far I like the product. There's been some debate whether you need to use the sealer, I'm convinced you must for it to be effective. Here's a link to a thread I started that provides additional thoughts:

Since then I've done a little test with the product on some scrap aluminum. I applied the A/B product on some parts, added the sealer over it on other portions, and left some parts bare Alclad or with the Alclad sanded off. I then wrapped the pieces with paper towels wetted with a strong salt/water mixture. Over the course of about a week I kept rewetting the paper towels.

Finally I rinsed the parts clean to eliminate the salt buildup on the parts. Appearance-wise the portions with the A/B/C and Sealer looked mostly good as new. The next best was untreated bare alclad. The portions with just the A/B product applied had a bunch of spots with darkened, rough areas. The sanded, untreated part was significantly worse.

I was a bit concerned about the sealer layer getting damaged during assembly and riveting. Although the sealer layer is clear, I don't think that's been a significant problem.

All-in-all I'm happy with the Sanchem product and plan to keep using it.
