NorCalDime Posted June 23, 2009 Report Share Posted June 23, 2009 80 seems kinda course to me... are you going to bare metal? Ive had a few friends sand down for respray and they used 320 and scotch brite pads to get the clear off and a uniform surface and then sprayed. Quote Link to comment
68 Datsun 51 DIME Posted June 23, 2009 Author Report Share Posted June 23, 2009 really?? when i bought this car there was 3 layers of paint it used to be a light brown color and a orange b4 this ugly blue! but im trying to primer it what do you think i should use Quote Link to comment
banzai510(hainz) Posted June 23, 2009 Report Share Posted June 23, 2009 (edited) if the paint your sanding was applied correctly all you really need to do is a light block sanding and the paint should stick good. 80 seem too much also. Norcal dime is correct on the grit coarseness but then Iam a spray can paint guy . But I did see the shop that did my yellow car. Most was just block sanding with higher grit sandpaper not to bare metal I dont think you want to use spray can primer. I heard their is a chemical in there to keep it from sticking to itsselkf otherwise iyt would not come out of the can correctly. ask a paint shop first they might have to sand the primer off again not to use professioanl paint of a spray can primer. I did a roll bar with primer and they said they had to sand blast it all off. I dont know and took their word for it. So I dont know how true this is.

NorCalDime Posted June 23, 2009 Report Share Posted June 23, 2009 your going to primer it then paint? or rock primer? If your gonna rock primer and sand down past those other coats of paint it is gonna rust from the inside out. If the body is straight and you dont have any issues that need to be filled i would just go over it with 320 and get a uniform texture all around and then spray it. If your gonna black primer it you would be better off rattle bombing it black with some rustoleum.... at least that will seal it up. Quote Link to comment
68 Datsun 51 DIME Posted June 23, 2009 Author Report Share Posted June 23, 2009 yea im going to primer it and then paint! Quote Link to comment
wag0n Posted June 23, 2009 Report Share Posted June 23, 2009 When I did mine I used a razor blade to scrape the old horris spraybomb job the previous owner had on there.. Then got to hand sanding. Started with 140 grit, worked up (or down depending on how you look at it) to 400 grit. And a little pneumatic sanding in bad spots.. (160 grit round sander) Primed her.. And finally painted.. My old 1980 210 I hand painted with a foam brush :) Quote Link to comment
68 Datsun 51 DIME Posted June 23, 2009 Author Report Share Posted June 23, 2009 sooo basically i need to start off with 140 and then go up ! Quote Link to comment
wag0n Posted June 23, 2009 Report Share Posted June 23, 2009 sooo basically i need to start off with 140 and then go up ! Yeah, you'll be sanding out the damage you've already done with the 80grit for an extra day of work.. Quote Link to comment
yellowdatsun Posted June 23, 2009 Report Share Posted June 23, 2009 80 is definitely to coarse. You'll be taking a while to remove the scratches you just made with the 80 grit. If you are actually trying to remove the paint down to the metal, use a chemical stripper. When I did mine I started with 150, then went to 220, and finally 400. Paint came out mirror smooth after that. Quote Link to comment
68 Datsun 51 DIME Posted June 24, 2009 Author Report Share Posted June 24, 2009 okay i just bought 150 grit i am going to start sanding it !:rolleyes: Quote Link to comment
marioburke Posted June 24, 2009 Report Share Posted June 24, 2009 150 is still too course if you are starting on paint that hasn't previous been destroyed by 80 grit. Wagon is right you will need a pnuematic sander with 150-180 to clean up the 80 grit. For the most part if you want to use primer you only need a good sander with 320. its plenty course. You can cut down the primer starting with 180 and smooth it out 240,320,400,600 and apply your sealer base and clear coat. If you have a SMOOTH surface (previous or factory color)to start with you that you just dont like and want it done quick and inexpensive 800 grit with a soft block will do just fine to lay down sealer or base coat. no problems. Dupont gaurantees for life if you follow the directions it gives you. Quote Link to comment
68 Datsun 51 DIME Posted June 24, 2009 Author Report Share Posted June 24, 2009 okay thanks ! i started on the hood today with 150.... :blink::blink::blink::blink: Quote Link to comment
steve g Posted June 24, 2009 Report Share Posted June 24, 2009 At this point use the 150, go slow and easy so you dont warp anything.... and the paper will last longer too... also make sure you feather the materials out nice (dont dig holes). im not sure what primer you will use but most do fine over 150. Once the primer is on , guide coat it and block it down with 400 and fix whatever flaws show up.... You kinda went crazy with the 80 grit but nothing serious dont worry. Steve Quote Link to comment
68 Datsun 51 DIME Posted June 24, 2009 Author Report Share Posted June 24, 2009 my neighbors joining in my dash u think i should sell it or keep Quote Link to comment
yellowdatsun Posted June 25, 2009 Report Share Posted June 25, 2009 The dash is a little hacked, and you'd definitely need a new/used replacement top pad, but keep it for sure. Finding another 69 style dash would not be easy, as they aren't nearly as plentiful as the later round pod dashes. Quote Link to comment
5casey1dimer0 Posted June 27, 2009 Report Share Posted June 27, 2009 Definitely keep that dash, fix er' up and put it back in. I love that style dash, they are harder to come by. Actually, sell it, to me:D Quote Link to comment
68 Datsun 51 DIME Posted June 27, 2009 Author Report Share Posted June 27, 2009 i have a surprise for you guys!!! and if you want the dash make me an offer Quote Link to comment

Yakuza Posted June 29, 2009 Report Share Posted June 29, 2009 thats NOT new, and its too much money.. Quote Link to comment
sssr20det510 Posted June 29, 2009 Report Share Posted June 29, 2009 finding an original 68 or 69 crack free dash is really hard, to the right person it may be worth it. At least you can get a cap for the 68 the 69 is not avalible, thats why i went with the z dash and to be differant. Quote Link to comment
pl521sss Posted July 1, 2009 Report Share Posted July 1, 2009 (edited) HERE IS WHERE I WAS GOING TO GET THE DASH! http://www.datsunlandsocal.com/index.php?main_page=product_info&products_id=440:eek: Ahh, Datsunland Mike Thought it was NOS dash I don't see him hoarding rare parts anymore like he use to in ebay. I got mine 2 months ago for $60 Mint condition, no cracks Needs cleaning to look like new If you do buy that dash Don't forget to buy authentic Nissan NOS 68 tail light assembly finding an original 68 or 69 crack free dash is really hard, to the right person it may be worth it. At least you can get a cap for the 68 the 69 is not avalible, thats why i went with the z dash and to be differant. There's always the overlay dash cap, if that's what your referring to. I did test fit from 68 and 69, fits just fine. Edited July 1, 2009 by pl521sss error Quote Link to comment
