I've recently traded in my Rx300 for a pre-owned 2008 Rx400h, and felt it was time to make it "mine".
One of the things i greatly missed about the Rx300 was the custom wood work i had added, along with dyeing of the wood trim to a more "red mahogany" color which i thought looked better than the stock brown.
The Rx400h interior trim uses the same wood and stain used in the 01-03 Rx300's. Although the shape of the steering wheel, shifter knob etc. are of different shapes, the wood type (walnut) and color are the same.
Before i started the re-dyeing process, i looked at the stock wood of the Rx400h, and noticed that the wood seemed somewhat mis-matched. All of the wood pieces on the console, door panels etc. are accented in a walnut "burl" veneer (identified by a series of rings and unique patterns, called knots) while the wood that makes up the steering wheel and shifter knob is of a straighter grain (grain is very straight without the irregularities and knots present in burl). This was going to bother me...
Although this mis-matched combination was also present on the Rx300, i wanted the wood in the Rx400h to match.
I began looking for steering wheels and shifter knobs that had more of a burl pattern to match the surrounding pieces. I found a steering wheel on ebay from a 2007 Gs350, that would also fit the Rx330/350/400h. The airbags+switches of the GS are different than the Rx's, but the frames are identical. The only difference is the wood pattern. The wood pattern of the GS wheels is of a cherry burl, which is a better match to the rest of the Rx's trim.
I also found a shift knob from an Rx350 pebble beach edition which has the walnut burl wood.
So now i was ready to begin! I didn't take pictures to show the steps it took to re-dye all of the pieces on the Rx400h, but there's a tutorial in my signature i put together to show how i completed the project on an Rx300 steering wheel. The hardest part of this retro was the removal of all the 400h interior pieces. I had to remove the interior door panels to gain access to the screws on the back. And the center console had to be taken apart, inside-out to gain access to the screws holding the wood pieces in place. It took me about a whole day to remove all of the wood trim pieces, and another to get them back on.
The process for dyeing all of the trim pieces (minus the steering wheel and shifter knob) is the same. I recently found a new way to stain, that allows me to keep the factory clear coating on the wood. I lightly sand the acrylic coating with 800 grit sandpaper, and apply a thin coat of krylon's red "stained glass paint". I then apply several coats of two-part epoxy clearcoat and let bake at 140 degrees for a half hour or so. Then i wetsand with 2000 grit sandpaper and polish with 3M's scratch remover to remove any imperfections and get that factory shine.
The process for the steering wheel and shifter knob is different because the factory acrylic coating must be stripped and wood sanded before the dye be used. This is to remove any "ring marks" that may be present in the wood.
So here's the results on the Rx400h. I took these pictures a few weeks ago and am just putting them up now. The wood in some of the images appears to be very "bright" but that's only due to the camera. All of the interior wood trim pieces are now the same color as the wood used in the 02-04 ES models. I really like the dark maroon color compared to the factory light brown.
Enjoy and please comment!
