    Filling Fine lines

     



    I've sprayed my frame and all my chassis parts with an etching primer as well as a 2k Urethane high fill primer and there are some fine lines I would like to fill. Do I have to sand it all off and then fill or can I just scuff it where I want it filled and spread some Evercoat Gold on there. I'll then sand and spray sealer over top before the color coat.

    Any ideas, if I have to sand it and start over I'll probably just leave it cause I'll probably be the only one to notice. I tried to put another shot of the primer but that's three coats and they're not filling in.

    You fill right on top of the epoxy and high fill primer. If the lines are really fine, use a finishing putty also know as Icing.
    There are no stupid questions. But I've seen some really stupid answers.

    Depending how bad those lines are, high fill primer may or may not fill them. Another product is polyester primer which is really a sprayable form of filler. A word of caution - etch primer isn't always compatible with all overcoats and is really '60s technology. A better bet would have been to have used a good epoxy primer on your bare steel, i.e. DuPont, PPG, SPI then your 2K. The epoxy is not water permeable though the etch MAY be and for sure, the 2K will be.

    Be careful with the poly primer especially if it's hot. It will set very fast and, from sad experience, will make a difficult to clean mess in your gun Use only about 1/3 of the catalyst at temps over 72-75*
