base with hardener
I've heard that adding a little hardener to the base paint is
a good thing. How much is recommended?
I use DuPont base,which is a conversion base, so I'm told,
so should I use the same amount of hardener in it as other bases?

Dupont Chromapremier basecoat takes a hardener.Dupont rep told me you can add it to regular chromabase. I did it for a while but didn't really see an advantage.Just another product to buy.Now if the basecoat calls for it i would say use it. I use U-tech polybase from time to time(awesome product BTW) and you have to activate it or it takes a year and a day to dry. If its optional i don't do it.Only time i use it is if its not getting cleared,like underhood colors(collision repairs) . Activated basecoats are a pain to sand if needed.They tend to gum up the paper.

Cut the percentages back on the hardener and it will sand better, your using to much.

I've always used just a capful, about half a shotglass, of hardener per ready to spray quart of clear. Use the hardener that will be used in your clear. Bob

BarryK suggested using it in Nason base to shore it up some which I've tried and it does seem to help,especially with adhesion problems IMO. Not sure exactly why,but I've had a LOT less lifting on tape pull's using it. Like bob said,about a cap full per qt. reduced.

Post whore huh? :mwink:

jc is probably like the rest of us,hanging inside in the A/C where it's cool spending quality time on the PC.
I'm about sick of this summer. :sweat: :sweat: :sweat: :sweat:

I was told to use a ratio of 16:1 and it would help especially on plastic bumpers for adhesion and flexibility.

A capful per quart is about what I heard, I was told that it would improve
adhesion of the clear coat. Sounds good to me,I'll do it.
This little thread whore works in a office all day so when I get
home I like to get in the garage and "sweat like a pig", it's been really
hot here with lots of humidity. I quit in the winter so I've got to
get on the ball, the work is piling up. Thanks guys for your input.

Maybe the cat he was using for bait rat fishing got after a big one and jerked him out. :D
