I do F1 models most of the time. I always use put down Micro Set first then the decal followed by Micro Sol, if they really don't want to lay down well then Solvaset will be applied. I use soft paint brushes to work them down and keep them wet at all times. On decals that have compound surfaces or folds I almost always use a hair dryer. If you have the new issue of Model Car you can see (page 50) the Haas F1 car that i did, I had over 60 carbon decals to apply and used heat on everyone. Look at the "HAAS" name and that has multiple compound surface, would have been really hard to do if I did not use heat, and while using heat I keep it wet with Micro Sol and keep brushing it many times back and forth. Don't be afraid to do this several times, on the carbon front wings I probably applied heat and Micro Sol 4-6 times per decal. Give heat a try and I think you will see how well it works.
