I decided to get the interior ready for the M2.8 seen as though the weather isn't great for spraying. I bought my products from Gliptone http://www.liquidleather.com/ What I ordered was a scuffmaster kit with 250ml of estoril blue and another 250ml bottle of black dye. Here's how my bolster looked before the treatment I Bought a leather rip repair kit from ebay as the bolster had two tears along the creases. This was a bit fiddly you cut a backing strip of the material supplied and poke it behind the rip, then smear the leather glue on the backside of the leather. Then you have to hold the two pieces while the glue sets I had an assistant with a hairdryer Next step is to fill the remainder of the rip with leather filler. I used a spatula and then wiped the excess with a damp cloth The next stages are pretty straight forward you scrub the leather with a gliptone cleaner and nail brush followed by wiping with a damp cloth. Next you condition the leather (I conditioned the bolster 2 or 3 times over a couple of days and found it helped remove the creases quite well) The next stage after this was to clean the leather again followed by a degrease ready for the dye. I applyed the dye in neat form in 3 coats so far to the bolster and this is the result. I still have the rest of the seats to do but just thought I'd post up my progress, so far I'm please its not perfect and you can make it out under close inspection but its a million times better than it was.
