Hi there. Could you please outline how you painted your fuel tank, like stage by stage? I am interested in how many coats you applied to get such a great finnish, decals under the clear top coat, just one top/clear coat? Many Thanks.
Depending on what metal you are using, steel, aluminum, etc.....
This is what I use:
New chrome plated tank. I cover the area to be chromed with duct tape. I blast outside of tank cause paint will chip and come off on the chrome.
Aluminum I sand tank to 150 grit for good bite. The panel areas I start at 220 grit.
Clean whole tank plus your hands with grease and wax remover.
Then mask off your panel areas.
I first use SEM self etch primer then scuff sand.
I then use SEM high build primer. I sand with 220 grit between coats. High build means it fills scratches, pin holes, etc.....
When I get all that done. I use a can of black lacquer paint to spray mist all over main areas.
I use 220 grit paper wrapped around a good level paint stirring stick. I sand tank to remove the black.
Any black left is a low spot. I keep using high build primer in area or some times use glazing putty to fill low spots in.
I do not use many decals. All paint work. The eurethane likes to lift decals and that's whole nother tricky process.
I retape my side panels use grease and wax remover on tank and my hands. I hang tank and use a tack rag, air gun, etc... To make sure no loose dust. Your compressor has to have attachments on it to trap water and I use oil trap filter. If not paint fish eyes.
Then I use Nason 2K epoxy primer sealer. Shoot whole tank.
Once cured, I scuff the epoxy with 320-400 grit paper and wet sand.
I retape my side panels, rehang tank and wipe down with grease wax remover.
I tag rag and use air gun.
So if I want a gold husky logo and gold pinstripe. I spray those areas of tank.
Later after base coat cures, I place my vinyl logo and apply my vinyl pin stripe. On pin stripe, I stick it to my shirt so tape is less sticky. I retape my side panels. I use air gun and tack rag on whole tank but make sure you clean your hands with lacquer thinner.
I spray my main base coat and let paint flash. I apply another coat and let flash.
Later using exacto knife. I sneak under the vinyl decals to remove them. When remove pinstripe, I pull straight back on tape. Keep paint from peeling and gives nice clean edge. The epoxy primer is what makes the paint stick as well.
I re tape my side panels then tack rag whole tank. Again, your hands have to be oil free.
Then I mix my eurethane clear up an I use a spot panel touch up gun. I spray eurethane at suggested air pressure and coat based on eurethane directions. Eurethane has to flash. On my next coat. I crank my air pressure up at gun to 55 psi.
This eliminates orange peel. I look into the paint as it hits the surface to watch how I apply it. Not heavy just a good, get it wet, even coat. Lighting is important and what ever you paint needs surrounded with fluorescent lighting.
There is an art to the whole process and took me years to learn. If I get a run, I have a technique to remove it while paint still wet using panty hose and thinner.
#1 use good automotive Refinish products(DuPont, Ditzler, Nason, etc..... Duplicolor over counter stuff is junk. As soon as you spill gas on it. Paint or clear comes right off.
#2 use a good respirator. The stuff in this paint, if inhaled can poison you or make your lungs stick together.
#3 Area dust free and well ventilated
#4 Must be no traces of any oil or water in equipment or on your hands.
#5 any coats have to flash. Means dry with any chemicals needing to evaporate. Or your next coat will lift.
#6 patience. Takes me about 4-8 hours just to paint a tank.
#7 it is expensive. Average paint and materials run me about $300 just for tank.
#8 when spraying edges along chrome side panels. Ease off on paint and clear. Because when you remove tape. Looks like it is 1/4 thick. Your pants are going to those areas and wear you paint and clear off. Or peel it.
