body work question

[grt222]

I build mostly short track race cars that body work is not as important than show cars but the problem i have is when i fill area's like panel lines on doors, trunks or 3 piece body seams it takes very little filler.I sand it so it is perfectly smooth, then when i prime it, it seems to show up or almost look as if it has lifted or sunken. What can i do to keep the body work underneath from doing this. I have been using bondo 801 glazing and evercoat glazing putty.Primer is usually plastikote,testors fine gray or tamiya. No matter which combination i use i seem to get the same results??? The panel lines seem to reappear after the next coat of primer or paint. Thanks for any help or suggestions.

Fillers requiring 2 parts mixed together to work may help with your reappearing panel lines. Good luck

Try brushing a coat of future over your body work before you primer. The future will seal it and prevent the primer from contact. The problem with glazing putty is that it's basically thick primer. When you spray your primer over it, it softens the glazing putty and causes it to shrink more. Also, try spraying two very light coats first and allow them to dry before you add any additional coats.

Try the evercoat 2 part spot putty, it's a little pricey, I think about 30 bucks for the pint size can but if you don't want shrinkage it's well worth the price. hope this helps!

I even use the CA glue to fill some, it seals and fills. Also sands out pretty well.
