body filler tips?

anybody got any god tips for getting a thin smooth layer of body filler, i have finished sanding my fiberglass and i want to put a layer of filler on it to make it perfectly smooth but mine goes on to thick and globby and makes for a lot of sanding.

not exactly what you questioned about, but along the same lines, if you have a small hole where you removed an emblem, you can fill that hole with a rivet, tack weld it on the back side & grind off the front side, this will lessen the amount of filler you have to use.....

using rivots and nails to fill holes is no right.....and as for body filler first off use good quality filler, and finishing putty catalyzed of course is way smoother than body filler. Then mix it right, and make sure you are in a warm dry place, smooth it on with the biggest metal spreader you can effectively use, and keep smoothing until you get it 95 percent. When it is hard but not totally dry body file it down, then hit it with the sandpaper.

an awesome filler is a bottle called metal glaze. it is green, the hardener is blue and it dries within an hour so that you can sand it. it fills pin holes and you can lay it over sanded paint or primer, although i recomend always going down to bare metal. it is a little expensive but well worth it.

same product i use! works killer.

.....like anything it just takes practice...yea a rasp and a fille will be your freinds while gettin the hangof it....when its still soft..but firm...u can take a knife and slice of any realy large imperfections...what kind of filler are you using..,,

i am using this on my dash, it was cracked and had three holes in it where someone had put some gauges and the spearker hole in the center was rotted out so i glassed it and it is pretty smooth but i want it really strait. i posted in the exterior section because i figured posting about body filler under interior would be confusing .

i saw this done on one of the trucking shows, it seemed like a good idea.
so if you don't use a rivet to fill holes like what are left when you shave the side emblems or for "elephant mirrors" what would you suggest using?

welding is the only quality way to fill a hole in metal.

i'm guessing you could probly use some sort of cold weld? like jb weld or something, it dries hard as rock, is machinable and paintable.....

yeah, that could be feasable....i'm just not to akeen to using body filler for every little hole, & the rivet thing seemed better than just using filler.....& i know if you tried to fill the hole by welding it up you would warp the you know what out of it!
