First thing first.
Your customer needs to have the trailer Brush Washed with extra detail on the Rear door.
Older equipment 5+ Years need a DeOxit wash. Fleetwash companies know what this is.
On day of Installation run the pam of your hand down the side of the trailer.
Your hand should not have oxidized paint on it. If it is a minor amount the dow a spot touch up as you go with denatured alcohol and terry towell. (get both at home depot)
Double down on the rear door.
Now your measurements are to be made from the lower aluminum frame. This is your One True Line
of measuring referance (typically 10.3")
If using Masking Tape you need the 3m Green Paint booth tape. its the only shlT that will stick
on a humid day,
Look for the lower reflector off the lower frame. That is typically C/L on the trailer.
Count your panels FWD panel is usually 49" the rest are 48" amd the Aft panel varies Add total and divide by 2, Bingo just like that you are C/L.
Get a Rollie Pro for the rivets. heat up a 30" run of the vinyl with hand held propane, and roll it.
Just like that you are done. Look up Rollie Pro on youtube. these fkrs work great and worth the money.
Yeah, I gots 30 years of these installations under my belt and cant do it no mo. Knees are gone.
Your turn.
Oh yeah on a 53' Trailer with 100" Panel heights do not make 1/8" measures smaller than 1/4"
heii no. 1/4 1/2 3/4 4/4. Make it easy on youself If it is a sinle line of text the 1/2" or 1"
Rear Roll up doors Wraps are best with Horizontal panels to avoid overlaps.
Start up top and snug up to the Drip edge.
WARNING WARNING WARNING
When wrapping a rear doors NEVER cover the Reflective tape.
If you do, then cut to the edge and remove the graphics to expose the tape.
If somebody rear ends the trailer, you can be sued in an instant!
