Synthetic High Temperature Automatic Transmission Fluid provides the gear protection of a GL4 gear oil in an Automatic Transmission Fluid and provides a higher viscosity at higher operating temperatures, allowing the transmission to operate at 70 Degree Fahrenheit higher temperature and still provide the optimal shiftability and improved torque converter efficiency. The evaporation characteristics are significantly improved, being twice as good as our Synthetic Automatic Transmission Fluid and five times better than a petroleum Automatic Transmission Fluid. The improved thermal stability significantly reduces the rapid evaporation of the Automatic Transmission Fluid which can produce a frothing out the filler tube. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum Automatic Transmission Fluids allows high temperature operation without varnishing valves and clutches which leads to transmission failure. High Temperature Automatic Transmission Fluid is perfect for heavily loaded vehicles which see high temperatures and automatic transaxles which are benefitted by the extreme pressure protection of a GL4 gear oil to lubricate the final drive. This product can be used in manual transmissions which require Automatic Transmission Fluids and will provide much better gear protection than a petroleum Automatic Transmission Fluid; however, MTL® will provide better wear protection and better low temperature shiftability in most manual transmissions which call for an Automatic Transmission Fluid. High Temperature Automatic Transmission Fluid is suitable for use in automatic and manual transmissions and transaxles where Dexron® III, Dexron® II or Mercon® is recommended.

A quality product which will clean an oxidized fiberglass trailer in preparation for the application of Poli Glow
I used this to remove the Poli Glow previously applied about two years ago to my fiberglass trailer. It seems to do a slightly better job of removing the PG than the other Prep solution, but I didn't do a side-to-side comparison. And the surface never achieved a completely uniform appearance after the stripping, although this may not be possible because of differences in the remaining gel coat surfaces. I also completely washed the trailer with soap & water after using this stripping product. I didn't do this the previous time and thought some of the prep compound may have been left on the surface resulting in a shorter life. Time will tell. Note: it is still "work" to strip the trailer, this is not a "magic" solution, thus the 4-star rating. But it, along with the Poli Glow, was the only way to get my oxidized trailer to look shiny. All the other products tried failed to bring a glow. I will purchase it again when redoing the trailer.

Does not work.
Do not use this product. It has left my RV all splotchy. It looks terrible. I am trying to find something that will work. I wish I had never used Poly glow to start with.

Must have for campers
This stuff is amazing! Made our camper look brand new with the polish they sell in this brand. Would use nothing else on it.
