I have used all the fillers mentioned above and currently use these two for now...Magic-Sculpt to build and fill up large areas and E7 High Density Green Putty P-04 for smaller gaps. Mr Surfacer 1000 and 1200 takes care of the scratchers when I prime. They work well for my aircraft, armour and figures.
