    Default Coating inside of pump parts and bowl?

    What do you guys use to coat the inside of the pump/bowl? Speed coat? How do you get at the inside of the bowl? The bowl I have has had work done and I would like to protect the aluminum with some kind of coating if possible. Heres a pic. Thanks in advance.

    There is a spray on speedcoat that you can use.

    I actually have a can of that. It just seems a little difficult to get at some parts of the bowl.

    Do you spray the primer first then speedcoat?

    I speed coated all the inside of my pump/bowl. I used the spray cans, apply in lot's of thin coats to avoid runs, but it's not that hard to get all the inside of the bowl, just go at it from both sides, you should be able to get half from the back and half from the front.

    john deere dealership parts depts sell speedcoat in a rattle can under the name "slipplate" "slipcoat" or some other variation, but its around 6-7bucks a spray can. as long as the part is dry and clean, the stuff will stick. you can't reapply for a wk later, if you try it'll release the fresh coat already on the part and spider up like you sprayed paint remover on it. i just bought a can from john deere last wk to speedcoat the bottom on my lil nitro rc unlimited hydro boat turned out looking pretty cool, haven't seen anyone speedcoat a rc boat yet, so i did it.

    Dare to be different, if it turns out great you can claim you planned it that way.

    Here's a thought! Water flows better on water then any other surface. So think of the area that you are going to work with and what will hold enough water to make a good flow. I have always got every thing as I want and then blasted for a porouse surface! Please correct my old school thought if I am wrong. Seriously! M

    a 3-m product ec-1945 b/a a 2 part mix that i believe is very similar to the original , i buy it at the airport, they say this is what they prime the aluminum parts with , have used it for years and it appears to be as near permanent as the original ,that i have been told was zinc chromate. this goes thinner than most other substances and adhears better than anything that i have used. for ease of use i also use a lot of the speedcoat as i have seen it hang on for a long time is inexpensive and easy to obtain from rex and others dries quickly and can be top coated anytime.
