 |
|
I've been cleaning my rusty fuel tank and made sure that the tank was turned and shaken regularly.
I did the following:
1. HCL soak overnight. Tank very clean.
2. Several water washes.
3. Marine prep soak for 4 days. Tank not so clean.
4. Several water washes.
5. HCL soak overnight. Tank is spotless.
6. Several water washes.
7. Metal Ready overnight.
8. Hot water washes. Tank has now a mottled finish.
9. Dried tank with hot air gun
Tank
Filtered the Metal Ready and got 2 coffee filters full of grey sludge.
I've never before used Metal Ready, is this what normally happens?

Welcome,
I wouldn't say it's abnormal, every tank has a different amount of crud in it and solution strength, temperature and time in use differes between users and jobs. If the end result is a clean tank with a slightly grey finish you've done good, a rinse with a little mineral spirits or gasoline just to get the last of the dusty stuff out wouldn't hurt and finish up with a bit of ATF just to prevent flash rust while it's waiting to be used.
