RV paint protection film removal

SST159 · 08-10-2025, 10:11 AM

Anyone find the best solution on removing the Diamond Shield and or 3m film from the front of a motor home. So far I have found the film removal comes off with the plastic razor blades. Very time consuming but its all I can find so far. Tried heat gun, steam etc. The bigger challenge is the glue underneath the film. That does not come off easy. I have tried 3m glue remover, prep sol, brake clean, W-D40, etc.
Appreciate any input or suggestions.

I had one in the shop to do last year went to Harbor freight and bought red chisel looking scrapers. You have to keep them sharp by sanding them but a heat gun and these scrapers get 90% of it off and then I made my own glue remover with diesel And 3M adhesive remover mixture
Be careful with the heat gun not to overdo it
And it still took two days good luck, buddy. That’s a tough one.

Hey Keith,
I did try the red chisel thing from Harbor Freight.
They were too flexible. The plastic razors work the best for me so far.
I also tried the heat gun and that did not help.
What does help is doing it in the sun when fairly hot out. (lots of cold beer on hand)
I do have two types of 3m glue remover.
One is in a can and the other is an aerosol spray.
The aerosol spray seems to work the best.
I will try mixing with Diesel and see if that works.
Thanks for the response.
