It's best to remove the conformal coating as it can contaminate your solder joint. Once it's removed, the reheating of the solder joints goes quickly. The conformal coating can be removed with Isopropyl Alcohol but it takes a while. Methyl Ethyl Ketone (MEK) is much faster but use in a very well ventilated area! IIRC, it's available at Lowe's, Home Depot, etc... in the paint department.
