Howdy guys-

If anyone could help me, I'd be forever grateful.

I'm putting on Clearcoat/basecoat urethane -http://www.tcpglobal.com/restorationshop/rsp2919.aspx
That kit should be all I need, right?

Any tips, suggestions, important things I should be aware of?

Please help!

Looks like this kit doesn't contain any sealer, which if your colour is similar and your clearcoat is still good on your truck you can do without. Problem comes a year or two down the road.
Just don't break through that clear when your scuffing the truck up.
Also you should get a wax and grease remover to clean the surface before you scuff and after you scuff. then again after you mask.
And a tack rag (not and option). Remove it from the rapper and let it breath for a day before you lightly tack off the car emediatley before base coat.
Do you have any body work?
