bob393 Posted November 9, 2009 Report Posted November 9, 2009 Hi: just got the motorcycle tank kit and followed the directions to the letter. My question is: when I look into the tank I see 2 bad rust spots that don't seem to dry. They appear waxy almost. The rest of the interior of the tank looks super, almost galvanized! I should note that I soldered the bad rust holes from the outside of the tank before I proceed with the cleaning. I supose it is possible that the waxy spots I see are residual flux from the soldering process. I dried the interior of the tank wit forced air cool and heated for about 6 hours and I assure you it is dry. How should I proceed with the spots. I'm ready to seal the tank but don't want a coating failure at this point in the project. Help Quote
KBS Jim Posted November 10, 2009 Report Posted November 10, 2009 It sounds just like you've described with the flux. Do you have any more AquaKlean left? Can you reach those areas with a brush of some kind? Quote
bob393 Posted November 10, 2009 Author Report Posted November 10, 2009 Just some of the old stuff I drained out. Do you think that still has some cleaning properties and do you think it needs to be removed for the tank sealer to stick? Quote
KBS Coatings Posted November 11, 2009 Report Posted November 11, 2009 Yes. You will want to get that out so that the Gold Standard Tank Sealer can adhere properly and give you the long lasting protection that you desire. Quote
bob393 Posted November 11, 2009 Author Report Posted November 11, 2009 Do you think the used product will still work or should I get some fresh cleaner and etcher? Would scrubbing it with a parts cleaning brush, not an easy task, help? Quote
KBS Coatings Posted November 11, 2009 Report Posted November 11, 2009 The RustBlast should still work. The AquaKlean should still work as well as long as it is not too dirty. Yes, you will want to scrub it with a parts cleaning brush. Quote
KBS Jim Posted November 11, 2009 Report Posted November 11, 2009 I worry that the sealer would not adhere properly to those areas. I would recommend some more cleaner & etch, and a strong solution 1:1 of the cleaner with hot water and a GOOD long soaking of that area. Any manual scrubbing of the area would definitely help. Then rinse and etch as normal before sealing. That flux can indeed be tough to remove. Quote
bob393 Posted November 11, 2009 Author Report Posted November 11, 2009 Will the aqua clean remove the zinc coating from the blaster? Will I need to re-etch the entire tank or just the two spot that I scrub to remove the wax? Quote
KBS Coatings Posted November 12, 2009 Report Posted November 12, 2009 Yes. It would be best to re-etch the surface with RustBlast. Quote
bob393 Posted November 13, 2009 Author Report Posted November 13, 2009 How clean does the rustblast need to be? I pored it out in a kind of dirty bucket, a bit of oil residue on the bottom. Quote
bob393 Posted November 13, 2009 Author Report Posted November 13, 2009 I'm still not happy with the two spots. I gave it a 24 hr soak and scrubbed it every couple hours with a parts brush and it still doesn't look clean to me. Perhaps a wire brush? Quote
KBS Coatings Posted November 13, 2009 Report Posted November 13, 2009 Yes. Go ahead and hit it with the wire brush. Quote
bob393 Posted November 13, 2009 Author Report Posted November 13, 2009 I'll try the wire brush. I ordered fresh chemicals so I'll start over again. Scrub, Clean, and Etch. I don't want to do this twice! Quote
KBS Coatings Posted November 16, 2009 Report Posted November 16, 2009 Sounds like a great plan. Quote
