want to make that old yellowed ABS armor white again???

 

the yellowing is caused by a chemical reaction in the plastic (caused by the flame retardant used in ABS reacting with UV sunlight) but fortunately this reaction is reversible. and can be done at a reasonable cost and effort (actually easier than buffing painting sanding ect..) just by making a gel called retr0bright (DO NOT USE BLEACH!!!!)i have never done this personally but you can search google for retr0bright as well and see tons of examples of this method in action.

 

this method is specifically for ABS plastic :)

 

watch this

part1

part2

 

read these sites

 

----------

 

i would make the gel myself

------------Retr0Bright+Gel

 

after whitening the plastic i would apply a spray on UV protectant wax

i found this info and thought it would be useful :Dremember to always use safety goggles :blink:try this at your own risk

 

science is FUN until somebody looses an eye

Lou be nice don't be like my step son Lou... :lol:

 

I do have the blaster and the holes are the speaker for ''blast em'' and ''move along move along''

sounds but he's a TD with no drop boxes !

Wanted to turn him into a TD since he's yellowing but Mason saved him . :)

pat.. just be careful not to get any cleaner in the speaker vents.. you might be safer to take him apart remove the electronics and clean the plastic parts individually

Yeah he's not lying. Bromine is used in ABS to make it fire retardant. Used in a lot of plastics as it goes

 

I'd like to see this done on a test bit first though......?

mmm too much work then i'll just turn him into a femtrooper !

Stupid question: does this mean that stormtrooper armour is fire resistant? :D

also note that if you do this you need to make sure it dosnt happen again

 

To permanently prevent the yellowing from returning, just coat the parts with a clear acrylic varnish. Alternatively, you could use a protective polish such as Armor-All or Autoglym to provide a UV protectant to the surface.

 

there are also uv protecting spray on clear coats as well
