MARTINSR I did a test one time with a very accurate digital MIL gauge used for measuring paint thickness. Cutting and buffing (unless you go nuts with it and sand more than you need) cut only a half a mil off. Depending on the clear you are shooting a mil or so a coat is what you are getting. So cutting and sanding in my experience with the clear I was using (others may differ) I got less than one coat removed when I cut and buffed.

And yes, I agree, FOLLOW THE TECH SHEETS! That is why they are there, it is clearly written in the tech sheets how long to wait.

Here is the recommendations from a particular PPG clear.

Preparation
Allow basecoat color a minimum of 30 minutes and a
maximum of 24 hours before clearing. After 24 hours
the basecoat should be lightly sanded before applying

I am NOT saying this is what you follow because I don't know what paint you are using. This is just an example to show you how simple it is, no guessing games, no asking someone only to get the wrong info, there it is in black and white. You wait a minimum of 30 minutes and a max of 24, clear as day if you'll pardon the pun.

If you google the brand name and part number of the clear you are using along with the words "Product data sheet" google should come up with it for you.

GMCTRUCKS I think it was Power Block TV that said that's how many coats should be put on.

hemi43 6 coats is way too much !! There's no way you'll remove 3 coats when sanding. With that many coats you run the risk of trapping solvents in the clear and you will have to strip and start over.
I've painted for years, so my experience is from trial and error not TV shows.

GMCTRUCKS I seen this show on TV that one should spray around 6 coats of clear because when one wet sands it you can remove up to 3 coats.

My truck is 19 years old and my fade paint job that was done at Trailmaster still looks real good I guess they must have used a good paint and clear. Since they just painted a fade job on my truck they didn't paint my hood or roof and look bad.

hemi43 The clear is usually sprayed within 30-45 minutes after the base.
If you want to reduce orange peel, raise the pressure of your gun slightly. You'll use more product, but you will get a better finish.
Usually 2 coats of clear will be sufficient, but if you plan on cutting then buffing, put 3 coats on. The trick that I use to tell when it's time to apply another coat of clear, is that I will stick my finger onto the clear (on a tape edge) . When you pull your finger away, you don't want to see strings. This usually takes about 15-20 minutes

DR327 This is a real easy one. Find out who's paint and clear your using and get product data sheets from them. Probably on the net. I use Martin Senour paint (NAPA) same as Sherwin Williams and they have them on their site for every kind of paint they sell, but all mfgs should. Stay with one paint system and follow their directions to the letter. These paint tech guys are good! They want your paint to come out good so you will tell everyone and buy more. A lot of custom guys say use someones paint and only such and such clear or primer which is fine if you've got years experience. If you are new to painting stay with what the mfg. says. You can't go wrong. Good luck with this deal. Hope it turns out nice.

Clear coat questions

Once the car has been painted with a base coat how long would you wait until applying the clear coat?

I ask this question because a few of the guys have told me they waited until the next day or so before applying the clear.

One of the guys had just done a base coat / clear coat job on his new Cobra and it really looked perfect with almost no orange peel in the paint.

When applying the clear coat how long would you wait in between the coats of clear?

Final question how many coats of clear two or three or more?

Thanks Jimbo
