We consistently RG-improve the 4D perturbative imaginary time formalism calculation of the scalar effective potential at finite temperature using the partial dressing thermal resummation scheme. This avoids overcounting, is easy to implement numerically using only one-loop results, gives results with high precision comparable to dimensional reduction calculations in the high-T regime, but is also under control and of useful precision beyond the high-T regime for strong phase transitions..
