I went this afternoon to speedy and referred another shop. I'll check it out first. Btw, since my r00f will no longer last i think (usable for the meantime no leaks or whatsoever, pangit lang itura may mapa ang humps).

Pwede ba (yeah metal sheet) sandblasted + powder coated?

Another questionL: pano pa nag anti-rust or prevent atleast sa casa? electro something, tma ba?
