First Tub Coat!

Finally got the first coat of Penetrol on the tub! After about two hours of scrubbing with a wire brush, scraping and blowing with an air compressor, I decided I got most of the loose paint off and it was time to start resealing and finishing! The penetrol should seal the cast iron and rust deposits and prevent future rust. The first coat takes about 24 hours to cure and then I will do a second coat. It just looks clear, but when it would hit the cast iron it would turn almost black. Anyway the tub looks far worse than it did before. As my neighbor always says to me, "You have to make a mess to clean up a mess!" Cant wait till it starts getting primed!
