How much time after clear coat to buff.

Hi guys, I tried a search on this but couldn't find what I was looking for. Last weekend I applied Omni 261 clear with the 264 hardener. Yesterday I purchased a buffer, glaze and rubbing compound. I was going to polish-buff today but have come down with the flu. My question is how long do I have to buff before the clearcoat gets to hard to work with? Thanks Jerry

I've color sanded and buffed cars that were painted years ago. the paint does get harder but it's not impossible to do.

Re: How much time after clear coat to buff.

I just painted Sherwin Williams base clear. The supplier told me to cut and buff after 3 days, and preferrably before 7 days. But I couldn't get at it so soon, and I did it about 30-45 days later, no problems. I did notice that is was easiest to buff the sooner I got to it, but I would say there is no end time limit. Harder clear is just harder to buff the 2000 grit scratches out. Takes more time and passes.

Re: How much time after clear coat to buff.

The longer the wait the better. If you wet sand the clear and then buff, the dullness may come back after the curing process has been complete. I would wait about 7 days before wet sanding and buffing. You shouldn't have any problems then.

Every now and then at the body shop we would get a car to return because the paint started to dull out. This was because we wet sanded and buffed the paint only a couple hours after getting the car out of the paint booth.

I like to wetsand the next day, then buff the day after. Get it at least wetsanded as soon as you can. The wife isn't sick is she ?

Re: How much time after clear coat to buff.

One thing that will help make it easier to buff, get yourself some 2500 grit wet/dry paper. I go in progressive steps, 1000 to take out nibs, 1500 to cut it flat, and then 2000 and finally 2500 to make it easy to buff. I would rather spend more time sanding than buffing. Be sure to use alot of water, and change the paper often as it will wear out pretty fast.

Authentication and pre-purchase inspection service still available. PM me for more information.
Still looking for that elusive 76 Nova SS.

A little dish soap in the water makes wetsanding easier also.

Re: How much time after clear coat to buff.

Thanks for the replys guys. I felt a lot better today and compounded it. This is the first time I have done anything like this and was amazed (delighted) to see the dull color sand finish turn shiny again. I can hardly wait to apply the glaze. After I was done I took the car hood outside and found a few more places that will need to be compounded again. I started on just the hood as being a first time painter I didn't want to do the whole car several times. It took me three trys with the hood but now I feel I can go on with the rest of the car with hopefully not to many problems. Yeah the wife is feeling fine, I heard ''what are you doing on my side" a couple of times tho. Jerry

Re: How much time after clear coat to buff.

Little trick when buffing is to kinda cock your head to one side to catch the light reflection while buffing, it'll help in getting all those sand scratches the first time.
