    have a 72 grill its in nice condition....
    but someone has painted it with nervous hands ...

    I think I could do better ...I test stripped the paint on back side with
    some thinner ...not good ...acetone ...forget about it ...and solvent
    cleaner eats up the plastic

    I have one guy telling me EASY OFF OVEN CLEANER and assures me to
    leave it on for one hour and then wash off .....whatever instincts I have is telling me that easy-off would be worse ....IS IT ??

    what to use ??

    :Do No:

    Re: stripping paint off platic grill

    Alot of us model car builders strip paint from old buildups by soaking them in Castrol Super Clean or Purple Power. Another method we use is 91% alcohol. Now the hard part is to find a container big enough that you could submerge a grill into, maybe a wallpaper tray or something along those lines would be big enough to hold a couple of gallons of CSC.

    Be careful and use rubber gloves because this stuff is wicked strong and will take the skin oils out of your hands and you'll end up with hands that look like something from a horror movie without protection or @ least have no more fingerprints left on your fingertips. It contains a chemical agent like lye so it is quite caustic to skin but won't harm the plastic like hot solvents such as lacquer thinner or acetone.

    The CSC works best on enamels while the alcohol tends to work better to remove lacquer paints. I've even forgot kit bodies in my soaking tub for a couple of weeks and then pulled them out of the CSC rinse 'em clean and they're ready for resto. Hope this suggestion helps you grill resto!

    I use EASY OFF on all my plastic grilles and fan shrouds without any problems. the lye removes the paint without harming the plastic. Easy off was the only thing that would remove the silicone mold release from one of the GSCA repro 71 grilles.

    I was going to post the same thread Frank. I have a grill has has a pretty thick coating of Krylon. I was going to try some Testors ELO on it, but I might try the Super Clean first. I was a little nervous about getting it media blasted.

    Let me know how it works out Frank. You'll probably get to yours before I get to mine.

    so I have to fill the bath tub up ....:laugh:


    I have it sitting in easy off and in a large plastic garbage bag ...

    media blasted ...?

    I was spying in Team Chevelle ...they even use brake fluid



    I picked up some krylon ...but after testing I think its to thick like

    * imo the best is that Eastwood argent metalic ...it lays and looks nice but
    the wrong color

    so I'm going with the Testors model spray paint its very close ..its all in the
    distance you spray from to get the right sheen/tone


    I have a hobby shop down the street ....the owner is like us but with 60's dodges
    he says sand with 400 wet and then testors black and grey prime then paint and no chemicals

    these grills are so tedious to do ...I will just strip mine and and paint later when
    I'm calm and in the mood for fine art at the point of its installation which is way off ...I'm just jumping around on the project and hate when I do that ...

    I've used easy off on plastics for years. Cleans it up nice without harming the plastic.
    Soda blasting works well too for pieces with lots of nooks and crannies.

    Dave and Bill are correct on the Easy off. I took this tip from Dave originally and have used it on alot of plastic parts since and it works. Just be careful and wear gloves. It melts your skin and makes it slimy. Pretty weird. I would not media blast plastic asit takes the sharp edges of the detail..........................Dave, did the GS club reproduction grill have the coating you mention? I managed to paint mine without removing it. I used plastic primer I think.

    Another vote for Easy Off - stuff is harmful though so do it in a well ventilated area, and wear gloves!

    As a model car builder - Easy Off is my best buddy! Does not harm plastic! If it only worked as good on ovens! :Dou:

    Re: stripping paint off platic grill

    I used the lemon scented Easy Off....:)

    50% of the paint came off ....after I used the power washer on it
    it became 75%....gave it one more night of easy off ..see what happens
    but I have some small areas of silver paint that is nasty to come off ..
    even with thinner ....I wonder what the heck it is that the last person that repainted it used ...



    soda blaster ??? ....never thought of that ...I thought they were joking
    with blasting it .....too late now almost done ...but for sure the next one
    these things are tedious as heck to do ..

    The GSCA grille had a Silicone mold release on it. I could not get the water to stop beading when I washed it with degreaser. The oven cleaner removed the silicone and the water laid down flat. The grille was able to be painted without any fisheyes.

    things together make 1 from 2-3 bad ones ....kudo's to them bcs

    sprayed the grill last night with Testors black ...3/4 of it cam out great
    had a section that bubbled up and fisheyed ....:eek2:

    stripped it clean again ...Practice makes perfect :Dou: taking it and smashing it crossed my mind for a split second ...but

    I'm guessing that it was the air I was blowing on it possibly ..
    drained the compressor and a lil foamy like moisture ....I have not
    drained it in a while .

    painted it with the krylon black bcs thats all I have ...looks good ..trick
    is the lightest coats possible...painted the whole thing black as someone
    else suggested and for the argent/silver/gray I am using testors silver over
    the fresh black and to be honest I tested on the rear and its looks and
    sprays out very nice over the black krylon and its seems to have the correct look to it ....


    *upon further screwing up ...that Testors has to go on light
    ...if you over do it ,it runs easy and it doesn't like other paints if
    heavy coats of it are applied


    and yes ..I'm the guy that likes to spray the whole can for one line
    and put my finger prints on it after 42 seconds ...when will I learn

    stripping, sanding (if required), taping, painting these grill to factory correct takes hours & hours. the repetitive taping is a killer.

    When I remover the original grill from that blue 72 I had, I noticed that the lower center black area was not masked off. There was black overspray on the bottom areas
