Megs 105/205 are great products. That being said, I am now a Menzerna guy. I use the FG400 in place of the Meg 105 and SF4500 for the 205. IMO Menzerna is a better correction product. The SF4500 will work well with your DA. I gave away my Megs because of Menzerna. Again, that is me...someone could disagree.
The combo of Menzerna is something to consider if you are looking for another product.
What he said! I tried the rest and menzerna is worth the extra money. I understand it is more money but if you figure out the difference per car it is minimal and so much nicer to work with. I have owned both and now only use fg400 for compound
