    Out of curiosity more than anything as I still have the Grumman what did it cost you including freight.

  2. G’Day Gav,
    Looks like your doing a great job. How do you find working with Prekote? What primer are you using? Is the adhesion good?

    • G’day! Thanks for your feedback.

      I find PreKote pretty easy to use. There are no noxious fumes and it works pretty well. I just use latex gloves but that’s more so I don’t get any oil from my fingers onto the metal rather than for any chemical protection. As far as adhesion goes, I haven’t had any problems. In fact, I notice that adhesion of the primer isn’t as good when I don’t use PreKote. I recall one part in my horizontal stabilizer that I missed PreKote-ing on one side. You could see the difference in the primer finish when I sprayed it on. The side that I did PreKote had the nice smooth, wet finish whereas the side that I didn’t PreKote was more patchy with some areas of the “orange peel” effect being seen. I tried to cover it a bit with some more passes of the spray gun. I managed to get the area covered but it was “orange peel-y” and didn’t look nice and smooth like the rest of it.

      I use 2-pack epoxy primer. From memory it’s got BMS10 or something in the product code. I’ve found there are 2 types of primer, self-etching and 2-pack. Self-etching (or 1 pack) primer is typically used straight out of the tin. This is the type typically found in spray cans also. 2-pack primer comes in two parts. You have to mix up a batch and let is stand for a while to let it react, then you can use it. You have to use all of it within a limited amount of time before it sets hard. There is a lot of debate on the forums as to which primer is better than the other. From talking to a lot of home builders, almost unanimously I was told 2-pack is better so I went with that. It’s more effort and you need a lot more PPE to use 2-pack (as it has very nasty carcinogenic chemicals in it) but it should ensure the plane will outlast me. Talking to the paint suppliers, I found there are 2 types of 2-pack primer also. Essentially, one type is for use on the internal parts of the plane, the other type is for the outside. At my supplier, the “inside” primer is green and the “outside” primer is yellow. I’m not sure what the difference is between the two but the your paint supplier may be able to assist.

      Cheers!

      • G’Day Gav,
        What engine/prop are you planning to install? What you think of Van’s deals on Lycoming’s?
        Cheers,

      • G’day!

        At this stage I am looking at an IO-360 with 2-blade FP. I may deviate from this and go for a 3 blade prop purely for cosmetic reasons. I’m a fair way from having to decide on this though. In a year or so I reckon I’ll make my mind up.

        I haven’t looked at any of the deals available yet.

        Regards, Gavin
