I will soon be painting a cowl, wheel pants and canopy edges. After reading countless posts regarding paint compatibility and fuel resistance with spray cans; I dont want to deal with trial and error - really the error part! I would like to get this done right the first time.

I have a few questions about Nelson Hobby Paint that I hope someone can answer:

1) The cowl I am painting is red and white, which will be painted all white. Do I need to use the Nelson Hobby Primer; or can I use something else that is compatible? Their primer seems to be about $23.

2) From what Ive read, using the Nelson Hobby Ultracote White and Clear will be fuel proof against 15% nitro - yes?

3) Can I get good results by brushing on with a foam brush? - If so, will I need to sand between coats or between White and Clear, if at all?

4) Are there any tips for using the Nelson Hobby products?

I'd like to keep this as cost effective as possible, but would like a decent result.

Thanks.
