Trunk Floo prep and Paint

finishing up installing the one piece trunk floor in my cuda. had to massage a few areas with the hammer to get contact on the frame rails for welding. planning on sound deadening material and some type of trunk mat/carpet. so my question is how much effort in smoothing welds and surface is really needed. its not sloppy by any means, but not interested in more grinding and filling either. any suggestions?
