I know there are serious painters on here, and I need some advice. I know that no serious painter would use a rattle can on their truck, but in the case of primer that comes in a can, what would be the best brand/type in your humble opinions? (Talking about covering metal that was taken down to the shiny stuff...) Also~ How long will these painted parts last, hung up in a garage, before it would be too late to paint them for good? The reason I'm asking is, I'd like to get a bunch primed in this beautiful weather so I'll be ready to paint by the end of May next year. Would this be too early? Many thanks in advance!
Re: I used to use a primer called "Gunk" brand. If you can find this its the best! I've had my 53 in primer for uhhhhhhhh,dunno how many years now,maybe 15 and its just starting to show a little rust.
Just bought some "Rattle Cans" made to order .... I needed to paint the dash and miscellaneous pieces. I'm not a painter. I decided to have 8 spray cans filled for me by: http://www.tcpglobal.com Their site is huge by if you navigate to the Auto Paint tab in the upper left, then find just below in the center the Auto Color Library, http://www.tcpglobal.com/autocolorlibrary/ they have thousands of colors and many validated by original matches. One thing I have noticed is to spray when the temperature and humidity are within recommended ranges AND not to spray too much each time. Several careful coats are making a huge difference in quality of coverage. I have been using Rustoleum Heavy Duty primer and their Heavy Duty Gloss and Semi-Gloss blacks. Once dried they seem to be quite hard and durable. It has been working well. Like many sprays, I am finding that if you want to spray again, you must do so soon after the first application or wait at least a day or so for full drying. Sometimes, depending on the weather I will "cure" parts in the full sunlight for a couple of hours. Haasman
If the parts will be hanging inside, out of the weather and humidity, they will last for a long time with basic primer. Just pick up some primer from the paint store and spray it on, it is much easier and better to just use a regular gun.
If the parts are going to be in the sun as in Arizona Sun, Rattle can beware of those fading blues. Reds fadee to a pink in a great big BIG hurry. The others colors just oxydize just as quick without some kind of hardners..
There are several primers available that will hold up decently to weather and moisture. Don't use the old laquer primer because it is good for neither and some modern top coat paint isn't supposed to be used over it. A quick spray with epoxy primer (available in rattle cans) over bare metal areas assures no rust creep from underneath and either polyester or urethane primer is good for a fairly long time. There used to be some enamel or non-sanding primer that was also weather resistant. No matter what you choose you MUST scuff it up to get adhesion for a top coat after it has sat for an extended period.
I've been wiring wheel cleaning most of the parts. In areas where that's impossible, I knock off as much surface rust as possible then used spay on a product like Gem Rust Killer. It dissolves rust, converting it into iron phosphate that forms an undercoating that inhibits re-rusting. Easy to use, brush or spray, no wash off necessary. The once rusty surfaces turn dark gray. Once the surface is completely dry, I then paint it. Haasman
Cool deal!!! See? I knew you guys could set me straight! Now that the colder air is coming in, humidity will be a non factor. All my parts will be hung on the wall all about my beautiful G. Thanks, guys! I appreciate it!
I'll check into this, also! Seeing as though I use a 3M wheel to get rid of the old paint, I have a few areas like this that I know I won't be able to get to. I'll see if I can find this and give it a shot. Thanks for this info!
Decision time Or you could just save that paint for something worthwhile and just let it die gracefully. Other uses for the paint = rusty trash can, old bicycle frame or lawnmower
