  • 2 Hinges :cracked paint repair update

    Upon using the vendors' "tool" to remove hinge pins, we placed blue tape on the top surface to help protect the paint and some on the tool. The removed tape brought up some chips of paint with it., unfortunately some on the top/ vertical faces. The chips didn't appear to be too well adhered to the primer, possibly too much paint build up there. However,we were able to delicately peel away the chips from the tape and super glue them to the substrate. Then with saved paint from last paint job (solvent based), we were able to build up the chip joints with thinned coats allowing the thinner/mix to work into the chips/ joints, etc. The last coat was overly thinned for blending. The process involved a few coats of build up and blending with a brush, then sanding with 600,1000 grit followed by 1500. The key element was allowing the build up to cure a few days and having compatible paint. A little more cure after sanding and polishing with 3M fine grit compound finished the job. We normally use an airbrush for small areas but this avoided that and extensive masking. We also tried (older ) Testors small rattle can clear coat for models on a test hinge and allowed it to dry a week to receive a polish. It fared surprising well because the spray pattern is minimal, it's a small confined repair area and the paint is not aggressive containing acetone like today's Rustoleum and other brands. Be interested to hear about others' techniques.

    Great information and helpful insight.

    I would recommend the next time, instead of putting the tape on the car, how about turning it over and putting it on the tool?
    You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

      We put tape on both. I did notice that the blue tape (non 3M) was a more aggressive tack so perhaps that was also the problem. It looked more like regular masking tape. Drafting tape (for engin. drawings, etc.) is a good tape for misc. uses and probably should have used that.

        by wrndln
        I need to touch up a few very small flaws in my front fenders. These are not the colorsanding break thru's I recently posted here on VFF. These are about the size of a straight pin's head. The fender are painted with PPG Concept 9300 black. I have the same 9300 black paint I am going to use to touch up the fenders. My question is: Will the paint I use to touch up the very small flaws work OK...

        Too much catalyst
        by BillLee/Chandler, TX
        What happens if you use too much catalyst when preparing some urethane paint? How does the paint react? How does it spray? Flow out?

        Paint in "Rattle Cans"
        by Bobm90
        I have always used paint in so-called rattle cans whenever painting metal objects was desired due mostly to the fact I never had a desire to own paint spraying equipment or had something large enough to require it, also I have - NO SKILLS. Although many people use good old Rustoleum I have never been a fan because it takes forever to dry to the touch, always seems soft unless it drys for days, scrapes...

        masking A to apply final black paint
        by JohnB15632
        I have been able to paint my A with the primary color, Maroon. Now I need to mask a lot in order to apply the black color.

        Would anyone be able give me tips, help, advise on how to apply this masking. Especially, how is the tape applied to go around corners such as the windows?
        Any advise would be much appreciated.

        Thanks,

        Trying to prevent paint chipping
        by wrndln
        I hope to start assembling some painted parts on my 29 phaeton soon. I am concerned about when I install the stanchions on the car (also the dash panel and some other areas), the 5/16" oval head machine screws might cause the paint to chip as they are tightened. I painted the stanchion over a year ago, so the paint is well cured and probably brittle and maybe prone to chipping. I was think...

        Now that we have the paint figured out...
        by DaWizard
        I have read the entire 32 posts on paint and what to use and I have a nagging question.

        What to use to keep the paint shiny and clean that will withstand mother nature. IF I paint my car, or have it done, in the near future it will still be stored outdoors in all the Southern Califlower elements, so I need to know, after I've spent these thousands of dollar on paint, what to use to keep

        How to keep lug nuts from chipping paint?
        by wrndln
        For the first two model A's I am restoring I had the 21" rims power-coated. The rims look pretty nice, but since most rims have curb nicks and other minor dings, it is hard to take care of the dings before they are power-coated. I tried using J-B Weld on the rims, which is suppose to tolerate temps up to 600 degree, but the J-B Weld still sagged some when the rims were heated during the powder-coating...

        Posted this on "the ***** ****" thought I may get some different opinions here. Anyone have good things to say about this or? Also is it necessary to use a sword brush to paint a strip when using this product or will any artists type of brush work?
