Kung "anal" ka, tatapyasin mo lahat and start from scratch. On the other hand, puwede namang lihain yung buong katawan para mawala yung tambok tapos bugahin mo ng pintura. The thing is, patuyuin mo ng mabuti muna iyan. Though the top might look dry, sa ilalim niyan medyo hilaw pa yung pintura. Nag-evaporate yung thinner sa top layer kaya natuyo agad pero basa pa sa ilalim. Dapat maraming manipis na buga rather than a few thick coats. At saka, malapit masyado yung spray gun/can mo sa body. Let the coats dry well before putting on the next one. Also, rather than have the body hang floor to ceiling, have it lie horizontally (you would need a bracket to do that).
