First time using DA polisher problems

Today I used a DA polisher for the first time. I used McGuire’s polish. Never go to the waxing part. While polishing I noticed the polish in some places dried to a film and was really hard to get off with a cloth. I’m wondering what I am doing wrong. The car was in the shade but today it was about 90 degrees. I only did about 1/3 of the car before giving up. Could the high temp be the problem?

Thanks

You mean a real DA polisher that looks sort of like a 5" grinder? Not the type they sell that looks like a mushroom upside down with handles on bot sides?

All I've ever seen and heard for such a problem is do smaller areas until you get proficient. Like 1/2 the hood, not the whole hood before moving to the next section. There must be hundreds if not thousands of videos out there on the "right" way to do it.

Vic is right. Small area at a time is key. Or, polishing compound will cake.
Either way, plenty of areas on any car that can be done by hand only. Might as well.

Harbor Freight DA polisaher. I watched a gazillion videos. Did a small 2' by 2' area at a time. Was wondering if the outside temp has anything to do with the caking of the polish.

The ambient air temp is not the issue but the temp of the sheet metal is.

I just did 4 cars and got out early so it was low 80's, no problem.

Car should not be done at any temp while sitting in the sun, should also not been done even after pulling a hot car into shade, it will need time to cool.

Hot metal and wax do not mix!

PS I use Meguiar's M20 Mirror Glaze Polymer , wonderful stuff!

Thanks for the info. The car was probably still hot when I worked on it. I'll have to wait a few weeks for the temps to drop. I get sun in my driveway until about 2- 3pm. I want to get it polished and waxed before winter. Once polished I'll probably only wax unless I get scratches.
