Hi Joe,
I would be very happy with tutorials of these works:
Repair of the pelled black glossy coating of the sail panels
Gearbox removal / assembly and synchro change
1mm to 3mm valve lifters upgrade
Sorry for asking too much but 
Joe, what present do you want for christmas? 
Greetings,
Óscar
Joes gonna be very busy according to your requests, lol.
Hi Oscar
I start filming engine videos in a couple of weeks and lifter replacement is on the list.
There are a number of different types of sail panel. I had not intended on covering respraying because this is not a job that should be done at home for safety reasons but I will be giving a few tips on how a car should not be done. If you let me know which type of panel finish you have, I will tell you what type of spray technique is used.
I have had a lot of requests about the gearbox but I am still unsure how to make a DIY video about a job that requires specialist tools and equipment. Some parts are no longer available and others are very expensive. I will cover what ever I can be sure is achievable by the man at home.
Thank you for adding lifter replacement to the list 
My panel is glossy black finish with Twin Turbo letters under the transparent plastic (1993 car). Is not ‘mate’ style, is similar to glass effect finish. Problem is, glossy/glass coating is too much pelled. If you could tell me the spray to restore the coating I will be very grateful to you.
About the gearbox job, I understand it is too difficult to do at home.
Again, thank you for your videos and dedication
Greetings
Óscar
I know this one. I have a couple to do myself on the red car that I will be using in some videos soon. I will show in a video, what to do.
I agree Joe getting the black shine on the sail panel would be great. I saw a post from someone who used the same method used when clearing the yellow plastic on headlights
