Metroplex G1 Restoration Question

[karmacows]

Hi,
I`m currently restoring a Metroplex G1 toy (Plastic wheels chrome stickers) and am in the process of giving him a hydrogen peroxide bath to remove the major yellowing. I have a couple of questions i hop you guys can help.
I`ve just bought the standard hydrogen peroxide from the supermarkets and are leaving them out for a couple of days in the sun and the plastic is turning out great. But i`m at the point of the legs and the helipad which have a few metal rods and i`m concerned that the bath will oxidise the metal rods. Most of the rods are one way and it would be difficult to use the soldering iron techniques as there is little to grab onto and nothing to pull (like the wheels).
Has anyone given had any troubles with leaving the rods/ metal parts (lower hip section) in place and leaving them in the hydrogen peroxide bath for a day or two?
Also, i was going to tape over the chrome parts of the plastic wheels instead of pulling them off with the soldering iron technique, would htis be advisable?
Sorry this is my first toy that i`m restoring and just dont want to stuff it up/ ruin him.
Any advice would be appreciated.
thanks.

Update 2
Well as said before hydrogen peroxide and chrome plastic are not good friends. Its pretty much stripped in about 2 hours using 3% H2O2. But good news is I used the soldering iron technique with success.
On another note, I`ve read on the web that some guys have been adding oxyaction powders to their peroxide mix. I can say that, unless its well mixed you`ll have all the powder remnants attach to any metal rods you cannot remove. I didn't have enough H2O2 yo do plex`s large grey legs in my new large bottle and as the town i live in doesn't open on Sundays i just added about 100ml of water and thought to add oxyaction to help with the process as the mixture had been used for the rest of plex so i thought its potency would be lacking. it helped but i found on every exposed metal rod i couldn't remove a nice paste of oxyaction. so after a scrubbing all good.
So now all i have to do is get some repro labels and hell be done. (Maybe in the new year)
