Hi, Steve -
Some time back I liked the idea of the handy little Valley Joe bottles and the product sounded appealing. I ordered a whole, great big heaping gob of the stuff, including all of their thinner and other items. Exciting to see it arrive, read up about it, then used it.
I'm glad others that have and are still using it, get results that please them. After giving it plenty of attempts to use, I quit and "came in from the ledge."
First issue was their advice to just roll it between your hands to mix. B.S.! I was getting very poor consistency that way, after lifting the nozzle off and stirring the bottom, I was seeing thick globs of Model Air solids on the stirring paddle. By stirring I got the stuff to a smooth consistency, then put in some tiny stainless nuts for shaking to ensure proper mixing for further use.
Next was dry tip, eventually finding flow improvers that did indeed help.
Then it stayed tacky and easily marked for a few days after use.
Next was the paint lifting with tape removal. Model Air primer offered no help in preventing that. Adios, Amigo's, I moved on.
The fact that others use Model Air with good results does not speak well for my attempts, but for whatever reason I just was unable to make it work for me.
For several years I've stuck with Tamiya, predictably good results, simple and straight forward. It can be thinned with their X-20A, lacquer thinner, IPA, all work well. Cleanup with same products.
