So I had the driver side bottom part of the box, behind the rear wheel well painted because someone hit it with a shopping car and took a nice chunk of paint out of it. :dunno: Now that I have my truck back from the body shop I have the 3m film I would like to apply near the bottom. When and how long should I wait? The paint was baked but at what temp I'm not sure. I won't be using my truck till next week but I'm worried about rock chips when I start to drive it again. Thanks for the replies in advance

:cheers:

Typically fresh paint should be allowed to cure for several weeks (in summer heat) before waxing. I'd assume the same could be expected for adding film. Wintertime temps slow the process. Check with the shop. Different paint suppliers recommend different cure times.

It's not temp that effects dry time and how good it cures. It's humidity. I would give it AT LEAST a week.

UNTRUE.

 

Temperature makes a huge difference. Warmer air speeds curing. When was the last time you saw a room temperature paint booth?

I like to paint in cold temps, the paint dries shinier from lack of evaporation of the ketones out of the paint while it's being sprayed. And I've never noticed any difference in paint dry time. Actually it seemed to dry faster when it was cold and less humid.

Not trying to bash you here, but any solvent evaporative process is effected by temperature. I'm not saying that paint can't be applied in cool weather (some like the way it flows due to the slower flash time) but when it comes to the paint curing, the warmer the better. Temperature most certainly has an affect on drying time.

You have to be mindful of not using too much heat as well. Ideally you want the drying to happen from the inside out, not the outside in. Too much heat will cure the outside, causing issues with the lower levels curing.

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.
