Body filler in the trunk?

ESP47 said
I'm replacing part of the trunk floor in my Barracuda. I butt welded the patch panel in. It's not perfect but I'm proud of it since I'm very much a novice welder. There's some warping here and there but it came out ok. If I want to get the trunk floor looking pretty smooth, would it be ok to use body filler here? In my garage, I have a brand new can of Evercoat Metal 2 Metal and a new can of Rage Gold filler. Should I place the Metal 2 Metal across the areas that were welded and then use the Rage Gold on the flat part of the panel? It'll never look perfect but I'd like it to at least look presentable if I have the trunk mat up. Then again if the filler is going to crack or cause problems back there I'd rather just not even mess with it. Thanks.

Well......... in our honest opinion, you will be just fine with the Evercoat Metal 2 Metal (we have never used the Evercoat brand) we have always used the USC all-metal with great success. Start with the Evercoat M 2 M over the welded seam area, just make sure you will have sometime after it is dry, to sand it down, as once you spread it on make sure you can sand it within a few days or it will be so hard, you will have to grind it off with a 24 grit grinding pad, especially if like the USC all metal! We have also used body filler ( a top of the line filler recommended) like you mentioned over the M2M filler with awesome results! This is how we plan to finish off the inside of the trunk floor on our 66 Chev Impala Conv. BB car. We have also used USC All-Metal on oil pans, valve covers, for many years, and its still there and looks great! Everything on body and so on, is prep, prep, prep, prep!!!!!!!!!!
Good Luck!
