Filling gaps
Posted by 58volvoV8 on Tuesday, June 9, 2020 9:31 PM

I'm in the process of converting a revell kenworth 900 into a day cab. I am putting a back on the cab and there will be some gaps from my not so precise cutting. I plan to back it with styrene...what would be the best way of filling the gap??? On hand I have super glue gel...testors contour putty and bondo glaze putty...any of these work??

I use Bondo Glazing Putty for larger gaps and Mr. Dissolved Putty by Mr. Hobby for smaller imperfections.

If the gap is large, relatively speaking, I would suggest the Bondo glazing putty or if the gap is backed with styrene fill it with superglue and cover it well with baking soda.  Neither will shrink later and cause an unsightly depression or crack.

I build models because I can't afford the real thing!

I would attack the gaps with a few rounds of gap filling liquid glue. Get those gaps as small as you can get them. For larger gaps stick a sliver of plastic in with gap filler and file down. The less putty you can use, the better. Putty should only be used for light cosmetics. 

The Bondo will not shrink over time and is the best choice. Make sure to apply it over primer or it will not bond to the plastic or properly cure.

My favorite color is clear. I am also ambidexterous, I can screw up equally well with either hand. I am 53 years old and been building for most of that time. :)

Hum...baking soda....would I fill the gap with baking soda and then put super glue over it letting the bkg soda soak it up?? Or use like a gel super glue and put it on top??......i plan to do the final smoothing in bondo glaze putty but this sounds interesting for the bulk of the gap.
