I may get a lot of backlash for this question but here goes: I am struglging to find anyone that is interested in working with me to paint my truck. Body shops are not interested in such a project. The option to paint it myself is a potential but I would need to buy a good/better paint gun (apparently the one I have is not considered up to the task), source the paint, and set up some sort of booth. Temperature control in the "booth" would be a concern depending on the time of year I actually get to the actual painting.
The other option is to use a readily available equipment enamel. While I should probably still construct a booth it seems that all of the other underside painting that I have done with this type of paint has been okay without it. One of the benefits of this approach is being less temperature senative and I perceive more readily available touch up paint availability.
I have great expectations of getting the painting done this year before winter sets in but on-going body work is making that seem less and less likely. I would really like to use the winter months to assemble all of the painted parts and start working on all of the after paint assembly required. I do have a heated work space but I do not believe I can use it to effectively control temperature during painting due to the nature of the heating system (propane fired buner haning from the ceiling).
