Re: tips to restore broken bakelite radios

apply bumper filler (for car bumpers) very hard but flexible (the picture appears on the bottom of the post , dont know why)
if you do not have bumper filler apply regular polyester putty or superfine polyester putty (auto body shop)

i added a reflective aluminium sheet to take the heat from the mains dropping resistor

next sand the filler with 120 grit until it is all flat and the correct shape, if you want you can use a sanding block
you cannot feel the transition between the patch and the rest of the radio
if you feel it then you need to sand more or add more filler and sand again (dont worry if you scratch the bakelite)
next sand the whole area to paint with 400grit wet sandpaper by hand till all the scratches are gone (easy)
then paint with automotive paint ( i use acrylic paint 2 components) super hard and unscratchable, never peels of for decades guarateed (about 10€ a quarter of a liter here and the colour you want)
next i polish the area not to paint, then clean it with alcohol to remove the polish compound residue and then i give it all a coat of clear lacquer (automotive)
then restored the electrical part of the radio and enjoy
this is a schaub libelle radio (nothing special but it deserved another live)

hi i will try google translate in the future but it doesn't seem to work very well in German so sorry if i say something that doesn't make sense Hallo Ich werde Google Translate in der Zukunft versuchen aber es scheint nicht gut auf Deutsch zu funktionieren. Tut mir so leid, wenn ich etwas sage, das keinen Sinn ergibt
