    Ok, im on the "touch-up" stages of a budget muscle car before the spring cruising time rolls around. i just fixed some panels and things, the car is getting some new paint, and is getting "shined up". I wanted to also paint the underbody. I may get it sand blasted, or atleast the major rust spots buffed out and sprayed with a pressure washer. My question is, which sort of paint is best for the following conditions?
    -not too costly
    -must be black, with fair bit of gloss
    -rust proof (preventative)
    -aerosol use
    -fairly good adhesion to most surfaces.

    I was thinking to go with tremclad rust paint, ive heard good things about it's rust fighting abilities, it goes on with a fairly good finish, and maintains gloss attributes. Any suggestions, opinions, and comments appreciated.

    Use PPG DP90 Black epoxy primer thined with about 10 % reducer to aid as a transfer agent so it will blow nice and settle with low orange peel.
    This will yield a perfect eggshell finish 25-30 % gloss which is a dead ringer for what GM sparingly used on undercariage of A bodies.
    Use a fresh air sytem for breathing as this product contains Isocyanates which will dissolve your nervous system.A regular charcoal mask will not cut it with this product.

    I guess it must be one hell of a product if it desolves ur nervous system. I like the attributes you mentioned, but im not sure if im up for a risk like that, i will probably be painting the car myself, likely outside in an open environment on a hot sunny day. Could you advise where i can get the safety equipment you mentioned, as well as the paint? Thanks.

    I would use an industrial alkyd primer and an alkyd semi-gloss or satin black paint over the top of it. It's very affordable, safe to spray with a regular charcoal respirator and very tough.
    What I use on both the bottom of the body and also the frame and suspension components is Keeler & Long brand. They have a few different color primers and the semi-gloss black I use is poly-silicone alkyd. I can do a little research to find out where it can be bought as it's been several years since I have gotten any.

    Sounds good, i will look up those brands and product names.I guess i can do the research on my own, but thanks for the offer. There is a NAPA paint fairly close to my house, ill bet they can answer some of my questions. Thanks again.
