Grant in West Oz Posted July 7, 2005 Share Posted July 7, 2005 I rarely wet sand primer with finer than 1200 grit. A bit of 'key' is needed for the colour coats to hang onto. Now, when it comes to colour sanding, you are all ready tooled up and experienced! G Quote Link to post Share on other sites
toadwbg Posted July 8, 2005 Share Posted July 8, 2005 I can't even find sandpaper finer than 1200 grit anywhere. Where do you get your finer grits? Quote Link to post Share on other sites
The Keeper Posted July 8, 2005 Share Posted July 8, 2005 First do a web search for the sanding grades you're looking for. Micromark.com carries some. When you buy a "polishing kit" its got a bunch of grades in it. Stores that cater to the auto paint industry sometimes have higher grade films. hth Quote Link to post Share on other sites
habu2 Posted July 8, 2005 Share Posted July 8, 2005 (edited) Would not recommend doing a search for wet virgins - especially if you're at work! Edited July 8, 2005 by habu2 Quote Link to post Share on other sites
Grant in West Oz Posted July 8, 2005 Share Posted July 8, 2005 I can't even find sandpaper finer than 1200 grit anywhere. Where do you get your finer grits? I purchased a packet of wet sanding sheets at an auto paint supply shop. Grits from 240~3200. Specialised finer grit sheets and cloths are available at plastics suppliers. There are quite a lot of items of interest to the modeller in such places. Bondo, knifing putty, pressure pack filler/primer, adhesives etc. G I couldn't find a sandy wet virgin but!

TexasBlues Posted July 8, 2005 Author Share Posted July 8, 2005 its been my experience that sandy wet virgins only appear in your dreams... or on girls gone wild videos... as far as the polishing pack goes, i found that at HobbyTown USA... they are from micromark so... youre saying that i should maybe rough up the mirror finish of the primer so that the new top color coats will stick?

Grant in West Oz Posted July 9, 2005 Share Posted July 9, 2005 so... youre saying that i should maybe rough up the mirror finish of the primer so that the new top color coats will stick? I dunno! I never got primer that shiny/smooth. To my mind, it'd be ideal for an Alclad II coat though! G Quote Link to post Share on other sites

Ant Phillips Posted July 9, 2005 Share Posted July 9, 2005 Am I the only one slightly disappointed by the content of this thread :( But coming back on topic, I find most gloss finishes are slightly self levelling, and don't require a mirror finish, on the other hand as Grant said ideal for BMF.

Andrew D. the Jolly Rogers guy Posted July 9, 2005 Share Posted July 9, 2005 A virgin can never be too smooth.What are you thinking? :P I thought at first you were talking about a virgin in wet sand. Hmmmmmm You're on a roll, my friend..... Quote Link to post Share on other sites

Raider100 Posted August 15, 2005 Share Posted August 15, 2005 (edited) I can't even find sandpaper finer than 1200 grit anywhere.  Where do you get your finer grits? I use the hobby kit put out by Micro-Surface Finishing Products, Inc. The hobby kit was listed as Micro-mesh cushions abrasives previously. It had sanding sheets down to 15000 along with a cushioned sanding block and polishing compound and cloth. The Hobby kit listed on the site currently only shows sheets down to 8000. Very good product. Can't beat it for polishing down plastic to prep for NMF. I paid $12.00 for this kit 13 years ago. At 16.95 it's still a bargain IMO. https://www.micro-surface.com/default.cfm?page_id=175#18 https://www.micro-surface.com/default.cfm?p...3khbk&storeid=1 Here is separate craft kit listed for $12.10 with sheets down to 12000. https://www.micro-surface.com/default.cfm?p...craft&storeid=1 Edited August 15, 2005 by Raider100 Quote Link to post Share on other sites
Waco Posted August 15, 2005 Share Posted August 15, 2005 Where's Kolja? This is a topic I'd expect to find an NFO lurking about... Personally, I think most gloss/flat coats require a bit of bite to settle in on the plastic. At least, that's been my experience. Too smooth, and if you have to do any subsequent masking, you're likely to pull up the undercoats down to bare plastic. Good luck. -Waco Quote Link to post Share on other sites
