Hi Guys I have a problem and I hope you can help, I am just an armature car guy trying to fix up my old ford t. I have filled and sanded and primed with a high build primer and rubbed it down. I have then put on three coats of black base coat and rubbed it down with 400 and 600 grit wet. The problem is I have a million tiny holes in the base coat do I rubbing down and painting base or what seams to me the best way is go back and put on much more filler primer. Hope this is not to boring for all you pro’s out there, my thanks in advances. Richard

looks like pinholes in your filler to me? I would mix up some two part polyester glazing putty, and using a razor blade
lightly skim over the pinholes with the glaze, trying to put less than more glaze on the surface. sand the glaze with a block until you cannot feel
the pinholes in the surface anymore, reprime, and then reshoot the base. Sometimes its hard to see pinholes in the primer without looking very closely at the surface. hope that helps.September 20, 2011 at 9:40 pm #33033Well, my thoughts are that you didn’t sand your primer enough and you are seeing the pitting in the panel and the primer texture.
Did you use a guide coat over your primer?
Freehand sand or using some type of block?
You need a little more bodywork in some spots too.

I would use 2k primer / with some guide coat then sand, seal, base, clear.
EDIT: in fact i would just go all the way down to the metal. then i would use that stinky primer for metal lol, 2k primer / with some guide coat then sand, seal, base, clear.

sure you can! but first make sure to prep those pin holes or whatever they are. use some putty with a razor blade and fill those (sand ’em), then 2k prime it. sand with 320, then wet sand with 600. seal it, base it, clear it.
PS: I rather just sand the whole thing all the way down to the metal (180sand paper should do it) and 2kprime. that way I know I got nothing to worry about once its primed. but thats the nice way to do it.
if you wanna half ass it then go ahead and do the putty glaze cover the pin holes, etc… The smoother it is the better. (final sanding with some 600wet, and seal it.)September 27, 2011 at 10:44 am #33209every thing is going ok, till i put on the 2k base and got orange peel, i have set the line presure to 30 psibut still get it, also the gun doe’s slater a bit i am going to get a clean up kit for the gun (divilbisflg) any ideas? :welc

Dont know about over the pond, but here the F.L.G. is a primer gun i have one it has a 2.0 tip for high build primer.
When we buy a new flg gun is comes with two tips 1.6 and 1.8 both of witch are too big for base and clear.
Though i am sure some could get by with that size of tip 😉
October 1, 2011 at 11:21 am #33261Hi there mate as you were one of the most helpfully guy’s out there, I am going to ask you which gun you would recommend to me to by, no pressure I need a good one to get the best results, but I probable don’t need top of the range with special functions (or do I) the devibis gti looks good. this is for base coat and clear, you were dead right about my FLG 5 it is for primer high build etc and it is a good one for that. I won’t bother you to much but any anvice would be great thanks very much Richard
