Yes I do understand. The painter here said most in Paint suppliers in England, will mix color from copy of example . In other words, you bring photo of color, they mix so color matches. I was hoping for original formula . Rusty, how many gallons did you order, ? And just out of interest, did you sand car down yourself? And long did it take? Did you use grinder and 4.5" stripping wheel?


That is a lousy way to try to match color. Photos are not accurate in fact the paint on the car has probably faded too. Take a close look at a photo and you will see several shades of color depending how the light or shade hits it. Now hold the photo next to the car and see how far off it is. Now run the photo thru a computer and printer and it will not even be close.

Why not leave it to the experts and just mix it to the correct formula? Why go to a lot of extra trouble to get the same result?

If you really want to do it the hard way find a sample of paint on the car that has been out of the sun and not faded. The inside of the glove box lid is usually good. Then match to that. You will get a more accurate match.

The Chrysler I mentioned belonged to my father. I did not paint it, the paint job was done in another shop. The car was a 2 tone job and it was a complete - door jambs, inside the trunk, under the hood , the lot. Also a 1951 New Yorker is a hell of a big car. As big as a Packard Patrician.

I believe the paint job took 5 quarts. One gallon of the body color and 1 quart for the roof. Plus hardener, reducer etc. This was a straight enamel job not base clear. The intent was to duplicate the original colors and finish as close as possible.

The original color combination was Quebec Gray and Haze Blue. This combination did not flatter such a big formal car. I would have loved to see it in black or dark blue, it would have looked a million times better if you ask me.

I have stripped the paint off an old car with a disc grinder. It is a very delicate art. You need to use a fine grit disc and a delicate touch. With a little practice I got good enough to strip off 4 or 5 coats of cheap paint and barely scratch the original finish but this was after years of practice using a grinder.

I have also stripped a car using nothing but a $3 razor blade scraper from the hardware store. The kind that takes a single edge razor blade. No I am not kidding. This was another old car that had several cheap paint jobs. The bottom paint job was not stuck to the factory paint very well. It was a simple matter to get the scraper in there and peel the top layers off in strips. It took a day or 2 to strip the car but no nasty chemicals were used. It was practically as quick as using stripper or a grinder. O yes I did have to use some stripper around the edges and places the razor blade would not reach.

If you must strip cheap paint off a car I recommend the razor blade scraper method. There is a knack to it but it is easy to learn. You can strip a car just as quick this way as any other you can do at home and it is by far the cleanest method as well as the cheapest.
