netters: H.B. Fuller mahes a lot of chemical resisting coatings. I used their products at Aerojet in Sacramento to protect or resist the attack on concrete by N2O4( Nitrogen Tetroxide) that forms Red Fuming Nitric acid when exposed to moisture in the air and Unsymetrical Di-methyl Hydrazine(UDMH) and to coat a floor to prevent pure Nitro Glycerine from being absorbed by the concrete which would tend to give the concrete an explosive personality foe a long period of time.
You might also check with "Carboline Corp" in St. Louis on Hanley for coatings. I would say just go with 5052 aluminum from the start if you can because I only see the compatability problem getting worse long befoe it gets better.
