    Hey guys. I recently got a Jupiter JTR 2000 (I think) it's a black Jupiter tribune. It's beautiful and plays so well but I bought it secondhand with chipped paint. I love the paint and wanted to keep it so I painted it with a flat back and clear enamel (my mum forced me to get the flat rather than shiny??) and it's now sticky, comes off, gets fingerprint marks etc. I need to sand back the paint and redo it. What paint should I use? Taking it to a professional is 100% out of the question so please don't say it. I can post photos if you want to see it, it's just a black trumpet with a terrible paint job basically. My dad suggested a shiny black car spray paint? What do you think

    it depends on how bad your paint job is, and what you have used. Maybe show us some pics.

    When you say it is sticky - not sure if you mean it is not cured, so soft, and easy to come off. No adhesion.

    The problems with Flat are exactly as you have described, handling will gloss it up where you handle it.
    You say you used Flat Black, then a Clear. Is that correct?

    ,,,,,,,,,,,,,
    First, strip it off. Nothing will adhere to what you have on there. It has to come back to brass.
    The suggestion to use a Black Enamel spray Can is OK. Not ideal but OK.

    It will need to be cleaned to remove any contamination, finger prints (yes oils from the skin can cause adhesion issues), so if it was me doing a cheap job, I would:
    1. Strip it to brass.
    2. Wipe clean with alcohol wipes.
    3. Steel wool lightly to give a key
    4. 2 pack self etching primer
    5. Black gloss enamel (preferably sprayed) or spray can.

    Will it last forever? No - but it will work. It may still chip.

    I have to jump in here and rebut the wipe down with alcohol wipes, my rational being that modern copolymer paints will not adhere well to it. In lieu thereof the wipe down recommended is white vinegar.

    The surface feels squishy, I can move it with my fingers, cat fur is sticking to it too, my dad said its dry but just screwed up when the two paints mixed. I used a matt black paint and a coat of shiny gloss, but the two basically mixed I guess. I told my mum about it and she's okay with me stripping it back and doing it over. Would car quality shiny black be a good choice? And yes I'd want to try spray painting it.
    Also I'm in Australia by the way.

    The fact that it is squishy means it has not cured.

    It probably looks a bit like a crocodile skin, as the two paints are not cured properly.

    I would go to Bunnings, you may be able to remove it with a solvent if it has not cured.
    Go to the paint department to start with and get an opinion.

    The Automotive Paint is expensive, and will require a full system of some type. It will also require spray equipment, etc.
    The Clear over Basecoat is an Automotive type of paint, and what you have done sounds like two incompatible paint systems. The Base coat has not cured, or the clear coat has penetrated it and caused the problem.

    I would stick with a Spray Enamel - as long as you prepare it correctly. It is cheap and will work OK.

    The 2 places to try first would be Bunnings or Masters. It will need to be removed, and cleaned before painting.
    Maybe a Car Repairer will do it, but seriously Car Paints are about 3 times the price of normal paints, and require specialist skills. The cost of Auto paints would be worth more than the horn IMO, but check with a Repair Shop if you want to...

    Where are you in Australia?

    Sorry Ed - WRONG.
    Automotive Pre-saturated Wipes for Surface Cleaning from Contec

    These are normally used to prep metal prior to painting - alcohol evaporates immediately, the purpose is to remove finger print or handling oils from the hands just prior to painting. Vinegar is Acetic Acid, so will work as a prep and a slight etch, but you are wrong to dismiss Alcohol wipes. Normal Paints such as Spray cans are an Alkyd based Polymer Resin.

    In any case, best to let the experts advise the OP. Bunnings is a Major Hardware Chain, and they can guide the OP.

    BTW - Bunnings don't charge anything for advice.
    There's one in West Botany, and another in Beverley Hills. Both are near you...

    If my memory serves, I gave you this advice when you first asked, maybe go take this advice now (?)

    Here's the address and phone number for a Dulux Trade Centre near you.... They will guide you in the right direction as well, and free advice.

    Dulux Trade Centre, South Hurstville, 02 9546 1216 - 587 Princes Hwy 2221, New South Wales - DULUX TRADE CENTRE, 0295461216, Australia - Australia - Top Business Directory

    So far, you can put the cost of the paint, the cost of the materials for removal, the cost of petrol for Dad to go take you around, the cost of time that you cannot practice - all tallies to an expensive exercise in NOT taking advice.

    Why ask the first time, when you ignore advice. If the store has supplied you with the paint, and they advised you to do what you did, then take it to them, they may honour the cost to fix it. Dulux are very good in this regard.
