I removed more of the dash and fittings from the car over the weekend. I also had a play with a spare cluster surround I had to see how easy it was to remove the wood grain finish. As most of you are probably aware, underneath that wood grain trim is the raw aluminium finish used in the GTR. Obviously the same piece was used, it was simply covered for the non GTR models.
It turns out thinners or gun wash is very effective! I tested this on my spare piece and it worked a treat. The only common problem is a lot of pieces have corrosion "worms" in the finish. I'm not sure if this is a result of the trimming process or what. The first piece I tested was petty bad so I decided I'd make something similar to a mitre box and line the base with either 1500 wet and dry or 3M steel pad then pass the alloy through to get a new uniform brushed finish.
I decided I'd remove the second panel last night more carefully than the test piece so I wouldn't damage or bend the alloy. I tried using a heat gun but it's not fantastic. It looks like a contact adhesive is used on the back of the alloy panel to fix it to the plastic. I ended up pouring some gun wash in between the alloy and the plastic and then waited for it to dissolve the glue. Not great for the plastic but I do have a spare which I plan on spraying.
Once the alloy was off I make up a make shift bath with foil and left the piece if for about 30 mins or so.
Once the thinners does it's work the wood grain cover is reduced to a balloon like rubber and simply peels off. It's a bit tricky to get off the edges but with some care it all comes off.
The contact adhesive also peels off the back
Once all the glue and rubber is removed, if you are REALLY lucky you might fine a virtually perfect aluminium panel like I did. It's still a bit grubby in this pictures so I'll brush it with some more thinners tonight and give it a good scrub. It has some very minor corrosion spots but I'm not going to both fixing them, if anything we may try and clear it.
A word of advice, make sure your bath doesn't leak. My garage is going to smell like a spray shop for a while
