    I was just wondering and have noticed a few of you guys are using primer. Is this needed to make the paint adhere better and if so, what type of primer is used? I'm getting ready to do the fuselage on my A-20 and am just curious and trying to keep from messing it up. I do realize that it is great for showing imperfections in the surface but I could use a flat color for that. Thank you in advance.

    Most people using primer are then spraying acrylics, which benefits from an enamel-type primer first. Although not 100% required if using enamel paints, a primer can be useful to achieve an even-coloured, smooth surface to work with.
    In this instance, a matt, or semi-matt light grey enamel, applied in an even, thin coat, works very well.

    So a light ghost gray will work then?

    Yep, should be fine Aaron. It'll also show any minor imperfections at joints, seams etc, which can then be rectified.

    That was the main reason for asking this question, I didn't know if I could use what I had or if I needed to purchase some actual primer. It works the same way on the cars, you do the welding and filling until your sick of it and then you prime it when you think your done just to find you've got more to do.:lol: Thank you very much Terry for your time.:salute:

    Not to promote a brand, but I use Tam...a Fine Surface Primer and it works very well not only because it helps find surface imperfections but also improves adhesion of acrylic paints.

    Same here. Ever since I pulled acrylic paint off with my masks I've used a primer, even if using enamels.

    Thank you very much for the info on the primer Alberto and Andy.The majority of what I have paint wise is enamel, with the exception of the metalizers which are lacquer. I have sanded the surface with 1500 grit paper so I hope this will be sufficient. The only taping I will have to do is for the D-Day stripes. Other than that it should be cut and dried but I will keep the primer in mind just in case I need it cause you never know. Again, thanks guys.:thumbright:

    You may want to use a piece of felt or newspaper to polish it up, better safe than sorry!

    I'm not good at explaining so......

    Doesn't have to be a NMF just to get a good painting surface. I do it before painting every time with a piece of felt.

    ABW, All I spray is acrylics and I have never primed. Though in a sense I quess painting a second time makes the first a primer. I also use a nail file block with four different grits: filing, shaping, smoothing and polishing to take care of any imperfections.
    as to pulling acrylics off of a surface I've found that while acrylics dry quickly they take a day or more to "cure" so if you're in a hurry the uncured paint can be pulled off

    ABW, I think you posted that you were using enamels so you have much more knowledge about that than I. I stick to acrylics and I think they do a nice job and you don't have the clean up or solvents to deal with. Plus I've never had a problem with adhesion once cured.

    Hi,
    I have a question on priming myself.
    What do you use to prime metal parts like p.e. or brass, i.e. landing gears?
    I use the Tamiya Fine Surface Primer, but it peel-of quite easily even if a wash parts with trichloroethylene before priming.
    Many thanks
    Alberto

    You may have to sand or scuff the surface of the parts to get the primer to adhere better but I'm not sure that this is all of the problem, it may be worth a try though. :cool:

    I'd agree there. It's also useful to dip the parts in vinegar, then wash and dry them, before annealing by gently bending as required. The vinegar removes the remaining coatings, if any, and with a lightly sanded surface, the primer should adhere a lot better.
