I’m curious as to what grit sand paper you guys use after priming? Also, how long should I wait before sanding? I used Testor’s enamel primer and it’s too thick in some spots. Any help would be greatly appreciated.
Thanks --Spencer[:)]
I use 1200 grit and only sand very lightly between coats. I only apply a thin layer of primer, just enough to reveal any spots that needs attention. If the layer is to thick you can sand it down and try to rescue any details that may have been filled with paint and then apply a new coat of primer. Good luck
Thanks for the quick reply. The highest I have is 600. Do you think that would do it? How long should I wait before sanding? The can says after 2 hrs.
No matter if its primer or color coat, I let it dry for a minimum of 24 hrs before I apply a second coat, sand or apply decals. Sniff your model, if it’s dry to the touch but still smells like paint, then it’s not dry yet.
Thanks, do you think 600 grit is enough?
600 might be a little bit rough. If you have a local NAPA auto parts store, try them. They usually have some 1000 grit. If not, go to a hardware store and get some very fine steel wool. That’s what I typically use in between coats. Just be sure to get reid of all the “Steel Fuzz” before the next coat [:D]
I have 8000 and 12000 grit polishing abrasives. They are great for removing finger prints, buffing a NMF, and leveling paint.

or you can go straight to the manufacturer —>http://www.sisweb.com/catalog/?page=A85
Walmart also has higher grit papers, up to about 1200, I think, in their automotive department. They’re smaller sheets, but they’re pretty cheap.
I saw Meijer had 1000, 1200, 1500, & 2000 grit in the automotive section. (with the bondo)
Thanks you guys. I was just in the Wally World auto dep. buying Castrol Super Clean, I didn’t think to look for sand paper there and they only had 150 or so in the paint department. 600 didn’t work too well on the seats for the Bradley. I was thinking they might not matter so much since they won’t be too visible, but other things like ammo boxes for the bustle rack etc., I’m definitely going to redo. Thanks Again -Spencer
The Wal-Mart here only has a package of sandpaper by 3M with sheets of 220, 320, and 400.

Did you try the auto section? I didn’t think to. All I found was the 3M as well. Ours does have three rows of craft stuff but I didn’t bother to look there either.
That’s a good point as they may have more there. I’ll look next time I am there.
I usually just go to a hardware store that we have around here as they sell it by the sheet up to 1,000 grit I believe. I never use anything above 600 though as I see no need for it.
Mike
oh yeah babe, they have whatever you need at walmart boys. the auto section definetly has the finer grit of papers. i also love those little plastic containers over in the crafts section. they are all connected and i think they come 24 to a pack for about a buck. they have a lid that stays attached to the container and i just cut them apart with my sprue cutters and mix paint or whatever else in these handy little jewels. they are about the size of an omni 5000 paint cup. there cheap enough to just chunk em when you get through with them, or you can clean them and use them again.
i swing by the electronics section and pick up a pack of those alcohol wipes for my computer that claim to put a negative charge on the plastic so dust is less likely to come to rest on the wiped area and leaves no residue to boot. heck, my small town walmart even carries a testors airbrush set! i couldnt believe it when i saw it.
the above is just a few of the items i use from walmart. however, i could go on and on.
later.
A lot of replies have been made since I were here the last time. Just to add to what I said in my first reply. I use 1200 grit between coats the same way MusicCity uses steel wool. If I need to remove a layer of paint or filler I use 600 grit. [tup]
Thanks monrad. I’m gonna get some 1200 or so today. --Cheers
Iwould try this product which works very well for stripping the primer. It would harm the underlying plastic and stripping the kit will allow you to give it another try. 
For more information go to the Aircraft resource Center link to read the review on how it works, where to get it and performance. I used it for a project come years ago and it worked as advertised.

Type-o on my part in the first paragraph…this product will not harm the underlying plastic. Sorry for the mispelling[:I]
Thanks for the links everyone. I got some 1000 and 2000 last night and I’m still…[banghead] The Castrol Super Clean doesn’t work as well as I expected it to. I got the paint off the small parts but I still have some other crucial areas such as a corner of the rear loading ramp, rear light covers and stowage boxes[banghead][banghead][banghead] as well as a couple of not so crucial areas like a small interior section and part of the lower hull. (Bradley M2 -Tamiya) Does anybody know of any step by step links that might help? Spencer[X-)]
How are you using it? You have to soak the part in Super Clean in order for it to work well.
