My little modified was painted about 12 years ago with DP90LF and it's getting dull and chalky looking. It's had road oils, dirt, WD40 and other contaminates on it over the years so I think it would be a bad idea to try to clean and flat clear coat it. I really don't want to repaint it! Does anyone have a successful easy way to keep an old DP90 finish looking good with a little shean to it??? Do any Wipe Down products work, waxes, Armor All, WD-40, any ideas or just live with it?

When I had a really poor paint job I was trying to milk the life out of... and didn't care much about at the same time. I washed it with comet and a sponge, took out all the oil stains and surface contaminants off, left it with a dull shine.
I had a 14 year old (DuPont) URO primer paint job on my 55 chevy, I just washed it good and sanded it down and had a friend spray on some acrylic enamel. Came out real nice.
Iv seen my Unkel Fred wipe down his car with a rag and transmission fluid. It was chalky and oxidizing and after the trans fluid it would look clean and shine. Not pour in on just enough to kind of hand rub it out would last for awhile.
Great idea about soakin it , only issue is when you do that money for your rod seems to leave fast ! [emoji848]
That is epoxy primer on your car. You can not restore the finish without re doing it. Your best bet it to cleen it good with dawn soap then wax and grease remover. send it down with 400 grit and spray it with SEM hot rod black. It's a single stage urethane so it will not fade and it will last a life time. I used it on my truck 5 years later looks like new still.
I was going to say steel wool but this ^^^ will bring the same end result. The WD40 was a bad idea, for paint that DP90 is going to have to come off and is the WD40 has made its way to the sheet metal, it will need to be pickled. Self Etching primer won't cut it. WD40 is good stuff for drying out a wet distributer and sometimes works on moving parts that are trying to seize. really bad idea for paint I am afraid.
I used DP 90 years ago,as we all know it's a epoxy primer and looks great when first applied but as time passes it gets chalky and looks bad,I love the look of primer but it just doesn't hold up. I used Kirker S.G. black on my pickup and it holds up great. HRP
You can actually buff it to a sheen, or wipe it down with Pledge. Here's a pic of a friends coupe that was buffed.
I've seen this stuff advertised, but never used it. http://www.ratwax.net/ Also I work with a guy that has a matte black toolbox and Snap-on sold him some stuff to maintain it called "matte and flat finish cleaner''. Smells like pledge though.
What Matt said....it's a good epoxy primer...not something you would put clear over...you can also have your local jobber mix you up some single stage with some flattener added to it
I've done the bucket of water and comet deal before, used a scratch pad from under the kitchen sink and just washed it. Left it with a flat finish but it was clean again.
Also to add I used a product made by wizards called wipe down it's for flat and semi gloss paints. It's what I used on my truck and works great!
I've got the paint problem on my A roadster. I used DP90 in 1999 and now it doesn't look anywhere near as nice as it did then. I think I will clean, sand and respray as well.
Panel prep Degreaser and scotchbrite, get a real scotchbrite. White is approx 1000 grit, rub in straight lines. Don't use an oil based product.
Of course you're going to get a thousand reply's about this but I would say wash it real good with Simple Green first. You want it strong, nearly full strength. What happens a lot of times is oils and waxes from all sorts of things contaminate the surface and change the way the paint reflects or refracts light. Especially on flat or suede paints and primers. Clean it real good and then make up your mind. You may be surprised how much it comes back to life.
