Learned about Crest from the old school of modeling back in the 60's.

Humm... play outside during the sunshine and model in the evening. 

Wow, many thanks to everyone...

a couple of oopses by me:

I had thought that Mr Surfacer (which I had used before) was mainly or exclusively  meant for resin... I have no idea why, thinking about it now it seems like an odd idea, but I really thought (probably because I've only sprayed it with resin) that that was its intended use.

I've done a bit with trying to chase into tight or detailed areas with a toothbrush, but toothpase as mentioned as a polishing compound, now that's something to look into as well. I'm guessing a little would go a long way.

I've also read that folks tend to like spraying a base of Tamiya as a primer for itself or other air colors, and again, this is sounding good too. Has to be much finer than the primer that I use, and I think some experimenting is in order.

I think I just have to go with there being no one priming step (if it's even necessary) that'll get me through all areas. Patience... tis the key, yeah. Got to realize that I'm not the only one who goes through this, just that when you see write-ups and reviews, it looks so darn easy!!! Well, not so much easy, but I guess I just don't have my 'processes' down yet.

Thanks again everyone, will see how today's fun goes (though... man, nice weather outside... sigh)

To model or not to model... what a question.

If you are having consistant problems with primer grit, try spraying a bit closer to the object. Usually grit is caused from atomized paint drying before it contacts the object so it can blend with the rest of the wet paint to self level.

I've never used such fine grit for wet sanding primer, I have had good luck using #320 - #600 grit. For those hard to reach areas I use cotton swabs or an old soft bristle tooth brush and some Crest tooth paste. The regular old Crest tooth paste (light blue stuff) acts as a polishing/rubbing compound, though a bit slow cutting (a bit like #4000 grit).

Good luck and patience is a virtue 

I use plain old Krylon white primer with good results for acrylic.. it never has had much of a problem with the grit being to low... In fact I don't think I have ever had to sand it even with glosses.

For Alclad I use Future with great results... can't get any more glossy than that!!

But if it is a finer grit you desire, Mr. Surfacer as mentioned comes in several different grits and I am sure you'll find what ya want.  Look on squadron or greatmodels and check it out!

You might try a soft bristle toothbrush and a "soft scrub" type cleanser. I use an automotive lacquer primer, and it works well for me. Or look at Mr. Surfacer threads on this site.
