    thanks guys, i guess if you have a part that needs to be coated all over, you have to have marks someplace from ground wire etc;
    i think i read after curing, you can spray marks while item is still hot & place back in oven & powder will flow out. is this correct?
    cheers

    If it's a small patch i've gotten away with brushing the powder on with a tiny brush and using a heat gun to cure it. Actually I was surprised at the results but it takes lots of patience and a soft touch.
    Also it is accepted throughout the industry to use tough up paint for hook marks and tiny blemishes. I don't like this approach but it is an option.

    Duke... you can "patch" in a spot as long as you're not trying for a show-quality triple-coat finish. You have the option of an IR spot cure, oven type cure, or scuff the whole thing down and put a coat on it entirely, re-bake and all will be fine. It's all dependant upon your needs... Russ

    recoating the whole frame is not a problem.
    the problem is getting the existing off. boo, hiss.

    I done a patch before, and it works best, at least for me, when it is in a "hidden" area, lots of curves etc...To help belnd it in. I did it with black on a quad frame, I sanded the area down real smooth like you would feathering paint in on a car. Taped off the area, but taped it to other "hidden" areas to help hide anything. Then sprayed and cured. Like I said the color was black, so I wet sanded it a bit to get rid of the tape lines, buffed with a clearcoat polish, then it was hardly noticable. Good luck

    You would most likely need to redo the whole thing unless it was not fully cured the first time, than it should blend in.

    started a topic patching up welds

    patching up welds

    if after a steel frame is p/c'd a weld has to be made, can we p/c just the welded area by using i.r. lamp? will it blend in with the other p/c if it has not long been done?
    or do we have to redo the whole frame?

    cheers
Working...
