    a week! I wouldn't clean, flatten polish or do anything to it for a week if you can incase chunks start coming out of it! I left my guitar that i sprayed and laquered on top a filler spreader thingy by mistake bout 2-3 days after laquering which stuck to it and pulled a small chunk of laquer away.

    5-7 days I'd say I think to be safe.

    Only reason i ask is because i rapped the bits up about 3 days after they were sprayed and ended up with the stitching pattern on the laquer.

    yeh, can do that just needs a rub down (wet sand) then use a compund to get all the scratches out (tcut or something like that) then polish to seal it! You should be fine with just a hard wet sand, compound and polish.
    But wait a week from application before you attempt it! otherwise your gonna be getting chunks coming off.

    tis risky though ain't it! feel free to risk the laquer coming off in chunks by all means. I've had laquer though that has dun that after 3-4 days (come off in chunks)

    i never use 2-pack as i don`t have any air fed gear to keep me alive,with cellulose and some heat lamps you can start fitting up after a few hours

    Not sure on the effects of heat lamps on celly 'cos I've not tried, but air drying you need to leave it ages. Even when its touch dry its not cured.

    2 pack can be cured out in 15 - 20 minutes.

    Thats one reason that pro bodyshops like it so much. You don't have to store a customers car for 3 days before polishing.

    You might well be able to do a quick polish on a celulose job in a couple of hours (yeah, I'v done that) but if you need to do any serious flatting on it you'll just break striaght through as its still soft under the skin. Yeah, I've done that too...
    Its better to burn out than to fade away. So long as theres not a police car behind you at the time...

    Nahhhhh cellulose takes next to no time to dry,it dries by eavaporation of solvents in the air.I`ve sanded runs out after a coupe of hours.

    Somethings wrong, can't be right I know yor all reffering to cellulose but the lacquer on my guitar it's been about 4 days since laquering and on the back where i've leant it against a hard edge it's left the indent on it! The mixture was perfect so I don't know whats going on. Too cold maybe when it was sprayed. Takes longer than 30 minutes be completely dry! Must do.


    This is 2pack mind! so I dunno

    2 pack will cure very fast with heat. Air dry you might have had the wrong type of laquer/hardener. Some combinations don't cure very well at room temperature. Even baked it will take a week or so to be fully cured (although it will be OK to polish once cooled from the oven).

    Cellulose will take a few days to cure properly, even when heated. You'd be surprised how long it will take for all of the solvent to flash-off. Don't know how long before it's OK to flat though as I have no direct experience using celly.

    Compressor sprayed laquer put on properly should be hard enough after a week in normal temperatures.


    aerosol, usually ends up going on too thick, I wouldn't touch it for a couple of weeks at least.

    Re: How long does it take for laquer to fully dry....

    Rubbing out runs for repainting and final finish polishing are two different things. At the risk of sounding like a complete bodger I use a 2KW electric fire propped up on an old subwoofer box to force dry cellulose to rub out runs or trapped dust in basecoats. 45 minutes and away you go.

    The thing is that the organic solvents in cellulose thinners take a long time to fully evaporate, especially when trapped by several layers of paint and clear lacquer. What happens is that although the paint feels dry and set it does cut back much faster and even if you donít rub through you have the problem that trapped solvent continues to evaporate and this dulls the finish. This isnít a great problem if its your own car as you just repolish a week or so later but if youíre in the trade the last thing you want is to return a car to a customer and have it dull out and then the customer isnít happy.

    Iíve also found that paint cut & polished quickly after application does not have the same depth of gloss as paint cut & polished the following weekend. This is especially true with solid colours. I did a hard top for a mate in gloss black and I couldnít get a good enough gloss buffing the next day, so bad I went through in a couple of places. So I reprepped and painted and left it a week. Following weekend it came up like glass with almost no effort at all.
