HI FASTERTHANLIFE!! Once the monokote has been spoiled it's never going to stick back down [as you know]. You've got to blot the soaked in fuel upwith something that is super absorbant. Corn starch made into a paste with GOOF OFF cleaning fluid and smeared on the wood will help suck out the oil. You could also saturate the area with GOOF OFF then smear the cornstarch over the wet wood and allow it to get bone dry. Sand the mess off, and feel if the wood is oily still, you might have to repeat this process. You can now brush on a thin layer of DOPE, POLYURETHANE, or EPOXY to seal the wood. Now you are ready to do a monokote patch. Seal the monokote with clear polyurethane furniture finish. It's a good idea to seal the seams of the covering before using the model. I don't get too fancy when repairing an "old dog". A down and dirty way is to do a good cleaning with MEK , lay on some contact adhesive, rearrange the loose covering [no heat], then go over the spoiled covering with clear 2" wide cellophane tape. You won't win too many model shows with this method though[&o]!
