i just destroyed my proline body at the BMX track with my savage flux :-) is there any kind of spray i can get to coat the under side that will make the body stronger?

Shoe goo or bed liner

Yes, theres a bedliner they sell in spray cans that people use. But Ive read its heavy.

Heavy wont effect the flux in any way...... Thats what I am doing to my body once I get the 2200 monster system in my X conversion

+1 for shoe goo and dry wall or PVC mesh. I also like foam crack filler if you have lots of room underneath the lid.
