SPI clearcoat instructions...6 coats???
 
I just read the SPI "perfect paintjob" instruction they had on their site. It calls for 3 coats of clear, cut/sand out the orange peel, let car set in sun for a day, then respray another 3 coats of clear.
Has anyone done this? Seems excessive.

Thanks

It is not excessive, its extremely excessive.
Its not for everyday painting such as collision work where you would do two coats and buff.

Everything in the perfect paint job is excessive for the solvent sake and trying to do a job that may need to look good for many of years if done as a show job or a high end Restoration where more coats of material will be used than a normal everyday job.

By the way the clear is made for mils like this where with every day clears this type of painting would be going back-wards for durability and depth and clarity of the clear.

Not for the faint hearted for sure.

Very interesting Barry.
I've read in some of the "LowRider" magazines where some of the
graphics paint jobs had 2 to 3 gallons of clear on the car.
And these are the little "rice burners"!!!!
How can they get away with that????
(I don't see how they install hardware, like handles & locks with
:pimp: that thick of paint)

Waaay back when
 
We used to shoot many coats of lacquer and then sand between coats to get that perfect shine..lot of paint wound up on the floor that way..

Graphics guys still do that sort of thing when they have lots of different colors in a design..

I RESTORED A 67 CAMARO SS LAST YEAR, HOUSE OF KOLOR ORION SILVER, 3 COATS OF CLEAR. WENT BACK THE NEXT DAY, SANDED ALL TRASH AND PEEL OUT WITH 600 MAKING SURE NOT TOO BURN THROUGH, LET IT SIT A DAY THEN 3 MORE COATS OF CLEAR, THEN CUT AND BUFF, YES IT MAKES A DIFFERENCE, I ONLY DO THIS TO CARS THAT ARE GETTING RESTORED, NO SPOT REPAIR OF COURSE, And EVEN NOT ALL OVERALLS IT IS ALL IN WHAT THE CUSTOMER WANTS TO SPEND AND HOW FAR THEY WANNA GO, BUT ONE THING IS FOR SURE, WHEN YOU USE THIS METHOD, THE CLEAR LOOKS ELBOW DEEEEEEEEEEEEEP!!!THANKS, MIKE.

Mike,
the bottom line is you may have the equivalent of 4 coats left when done with all your sanding and buffing.

People that do this kind of work sometimes will block the first three coats with 400-600 and then a second time with 800 before re-clearing.

Some will wet sand with 400 - 800 and then wet-sand with 1000 and then 1500 and then 2000 before buffing.

This probably should not even be on the web for general view, but the decision was made to do that because even if someone is doing just an everyday two coat paint job there is a wealth of education in the article as far as flashing solvents, dry times and proper grade of reducers in the base for maximum clarity and how they affect the final job.

So................for most paint jobs, even ones that would be considered "show", 3 coats would be more than enough???
I noticed, also, that the SPI instruction recommended spraying all wet coats. I did not see where they mentioned a "tack" coat.
I can just envision the runs I'd make.

I'm seriously considering their paints. Really wish they had an orange or two to choose from, instead of black, white, and reds.
I'll probably go with black. I know it shows everything, but I figure for the small garage I have to use, I will spray in pieces and reassemble VERY carefully.

There is an old saying, if you ain't got no runs, you ain't applying enough clear.

Keep in mind that runs can be sanded and buffed out. If you have a dry spot when you are done, then that is a different story.

I have sprayed alot of SPI HS clear and it is very hard to get a run. You would have to try real hard to make it run. I tried to spray some Diamont DC92 to get rid of the little bit I had left over. I applied it just like the HS nothing but runs.

They're not talking about runs like yours where the entire
side of the car is dripping and puddeling on the floor.
When you have half a gallon of clear on the floor that's spraying to
much. :pimp:
