I actually got a very acceptable $60.00 paint job on my race car by using Valspar paint, available at Tractor Supply Company. I did use a cheapo spray gun rather than a roller. Now that race season is over for me, I'd like to get some more durability and gloss by "clearing" the car. Is there any clear that is preferred to use over the enamel? What about a 2k clear. I have already water sanded with 600.
