Does anyone know how much weight you can save switching an old car from enamel to lacquer paint?

I would say none, It all depends on "Coverage" and by that I mean with some colors it takes two coats for coverage and others it takes 7 or more coats for coverage. Thats just with the paint, if your are just going to respray it will be added weight. If you want any weight savings through body work you will have to strip the car down to the metal and 'properly' repair any damage ( ie. minimal, if no body filler) and change any original panels to aftermarket or reproduction replacement panels, and very minimal amounts of primer. If you were asking about modern base coat/ clear coat systems I would not use any "high solids" clear coats as with our Sikkens brand paints I have seen a noticeable increase in the weight of the cans that get delivered. This is all paraphrased but to sum up I dont think you will see any reduction for the costs that will be involved.

a lot depends on the ingredients of either one--- cheap ones will be lighter in weight and the better quality paints will weigh more simply because of the ingredients----lacquer weighs about 6-7 pounds per gal while enamel is about 10-12 per gal--- remember tho that enamel is more durable while lacquer will chip easier---also consider the primer used primer can be heavy about 11-14 pounds per gallon -- price will be cheaper for lacquer and easier to apply while enamel tends to be pricier and more difficult to have a good finished results

The cheaper paints are cheaper because the have less pigment in them therefore it will need more coats for proper coverage. We do race cars all the time at our shop where weight is a consideration and we just use our modern Base coat/Clearcoat systems and still achieve the necessary goals for weight loss. The key for light weight in body materials as far as fillers ,primers , and paints is that less is more. Meaning that 1-2 coats of primer only when necessary, 1-2 coats of paint or color, and the bare minimum for clear coat, with a color sanding and polishing afterwards. The most gains are when the old fashioned grinder is used to 'Thin' out the base material.

You might want to speak with someone that is qualified/licensed to paint aircraft: Weight and balance are obviously of interest in this area.

Aircraft painting is a good measure, on a DC-7 painting from the windows down including the lower belly, a 2 coat coverage would be about 600 pounds of weight. One reason you usually saw them painted only half of the plane. That being said a standard refinish of a midsize muscle car of say a normal silver color would be about 6-800 grams of base coat ready to spray and around the same amount for the clear coat, I know you are asking about enamel and lacquer, I bring up these amounts of Base/Clear only as a reference number for comparision and that is what we spray on a daily basis. All of our mixing is done on a scale for accuracy in color match

A number of years ago Dale Armstrong (Budweiser King) was concerned with weight and the painting of the frames on their top fueler.....he weighed the frame before and after painting and there was very little difference in weight....most of the weight in gallon of paint is solvents which flashes off after being sprayed, the actual pigment left behind weighs very little......

Whether you use lacquer or enamel it will take 1/2-3/4 of a gallon to coat Dart or Nova. Get a gallon each, weigh them and do the calculation.

What about the 30lbs of stickers you guys run to get your contingency money? LOL.
Maybe you could leave the car in primer and then have one of those companies do a vinyl "Wrap" for your car in whatever choice you want to and have the wrap include all of your contingency stickers that you want to run. |
