I just did some of my parts this past weekend. I brushed it on and it flows out really well. If you brush it on, don't do it in really hot direct sun. It will flow better if it is a little cool.(I did mine outside)If you spray it you better follow safety instructions.It contains isocyanates and when sprayed is a lot more dangerous than when brushed. I know a couple people who have had isocyanate poisioning and its no fun not being able to breath.

The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
